This is a list of pages with popup previews which are not as Nature intended. Please feel free to add more pages you find, and suggest fixes to my regexes if you're into that sort of thing.

• Ton (society) : (as seen from Georgiana Cavendish, Duchess of Devonshire, find " ton " then hover)

Preview appears as

A variant of the French bon-ton, a now-archaic expression designating good style or breeding, polite or fashionable society, or the fashionable world, tons first recorded use in English was according to the Oxford English Dictionary in 1769.

where the article has "ton's first" text coded as

''ton''<nowiki/>'s

Or perhaps, is there a better, less distressing way of coding ''ton'''s (italics followed by 's ) in the original text of Ton (society) ? Shenme (talk) 02:12, 30 October 2023 (UTC)

• Kuyavia : the displayed image is not the geographical map (or the coat of arms) but of the "A1 highway" (which is part of the infobox) Halcyanide (talk) 18:51, 1 May 2022 (UTC)
  • Fixed. - Einstein95 (talk) 01:04, 7 January 2023 (UTC)
• CAP computer displays part of the File link in the preview.–OrangeDog (talk • edits) 19:53, 29 January 2009 (UTC)
• This change displays the wording backwards/reverse (in Firefox 2.0.0.18 and 3.0.4). Dl2000 (talk) 18:23, 16 November 2008 (UTC)
  • That's the actual edit itself. That IP used a reverse text tool probably. The actual problem is the preview doesn't recognize the reversed text has changed. Maybe it doesn't compare the order of the text. - M0rphzone (talk) 05:52, 6 April 2012 (UTC)
    • The edit added a right-to-left mark which makes the text be reversed. - Einstein95 (talk) 01:04, 7 January 2023 (UTC)
• Retired husband syndrome gets the sentence "It is a condition where a woman begins to exhibit signs of physical illness and depression as their husband reaches, or approaches, retirement.[2]" repeated twice. Josh Parris 01:01, 22 September 2008 (UTC)
• The # (edit count) link for people's user pages doesn't work (for me, at least). It Is Me Here (talk) 19:14, 3 September 2008 (UTC)
• The popup version of Ancient Rome contains no text. It Is Me Here (talk) 19:13, 3 September 2008 (UTC)
• http://tennisfcb.de/wiki/index.php5?title=Trainingskontingente_2008 - Navpop does not render the <div-Tag right. All content within the <div-Tag (it creates a nice yellow frame around stuff) is skipped.
• http://en.wikipedia.org/w/index.php?title=Template:Non-free_use_rationale <- something isn't right with this, I think - hover your mouse over it and the popup just contains a load of screwed-up wiki/html code type stuff. It also happens sometimes with the 4 links on that page - "Portion used", "Low resolution", "Purpose of use", "Replaceable?". It doesn't seem to happen on those links in the template page itself, but it does when the template is used elsewhere, such as http://en.wikipedia.org/wiki/Image:Bbcnews24_bhuttokilled.jpg (and for that matter this link says "image query failed" as well!?!). I hope this is a real bug and not just me doing something wrong, I'm very new to Wikipedia so apologies in advance...
• S. C. Johnson & Son ends abruptly.--Gkklein 23:27, 19 December 2006 (UTC)
• North America - triple] confuses Previewmaker
  • These should be working with the dev version. Lupin|talk|popups 14:25, 10 December 2006 (UTC)
• Wikipedia:Browse - odd page, but just gives |}
• Great Googly Moogly - blockquotes are problematic (currently they're just deleted).
• User:Wiki_brah - I only get the first two words previewed while I'm set to receive the first 6 sentences. Maybe a problem with the exclamation marks?

  [Thanks for being the first person other than me to add to this page!] This is because we extract the first two pars only. Here, the second "sentence" doesn't end until the third par.

• Singular they - livepreview bug, methinks

  With blockquotes again Josh Parris#: 03:19, 9 January 2007 (UTC)

• Whose Line Is It Anyway? - question marks give in main link

Note: works in Opera, Konq and FF; ? ignored in IE

• Wikipedia:Wikipedia_Signpost/2005-09-12/Anti-vandal_tools - very long thin image needs to be tamed!
• User_talk:MathKnight#Coastal_Road_Massacre_images Intra-wiki links (e.g., [[he:...]]) are ignored (missing) in the preview.
• When previewing reference markers, the preview should supply the relevant endnote text, just as it currently does for foo#bar - an anchor bug, methinks... altmany 10:22, 1 February 2006 (UTC)
• Krav_Maga#Haganah - When previewing a sub-section reference (foo#bar), then bar's section-top image (if present) should take precedent over foo's page-top image. altmany 10:22, 1 February 2006 (UTC)
• Ed Green: most of the time the popup content doesn't show up. Especially when accessed from my watchlist. I got an empty little square, or an empty rectangle (normal popup width, but no height). Lvr 09:59, 28 February 2006 (UTC)
• Section stuff broken Lupin|talk|popups 04:53, 2 June 2006 (UTC)
• Dixie (song), Alexander the Great - currently choking on <ref> tag and stopping preview at that point, rather than stripping. -- Mithent 02:33, 25 June 2006 (UTC)
• diff pages with commas seem to choke it, the regular pages with commas work, but diffs of those pages don't. Can provide other examples if required. BTW, this is a nifty tool! :) Umeboshi 02:53, 15 December 2006 (UTC)

Which browser? It seems OK to me in firefox. Lupin|talk|popups 09:21, 15 December 2006 (UTC)

I'm using Konqueuror. Umeboshi 14:53, 15 December 2006 (UTC)

• [Radial had a link with a trailing space] - Wikipedia truncates the space, popups doesn't... when it lists the disambiguation options. As an additional joy, the link with the trailing space was linking back to the same page - Radial. I'm not sure what you ought to do with this one, perhaps ignoring the problem wouldn't be unreasonable. Anyways, now you know. Josh Parris#: 04:40, 7 January 2007 (UTC)
• roboticist - 3 apostrophe marks begin the term but don't end it. The wikipedia page looks fine but the preview is all bold afterwards. Don't know if that's a bug or not Ygfperson 03:00, 11 March 2007 (UTC)
• Spice 1 misses the hatnote (probably by design) and the entire first paragraph. Josh Parris 05:41, 23 March 2007 (UTC)
  • 'Fixed' by changing hatnote to use ((dablink)) instead of just "''hatnote text''" on a line by itself. —Resurgent insurgent 2007-04-13 03:12Z
• Wikipedia:Tools/Navigation popups - The preview ignores the subst template and then shows everything afterwards as plain wikitext. - MTC 10:21, 31 May 2007 (UTC)
• Talk:By Divine Right - with "popupPreviewKillTemplates = false;" the WPBiography template is not shown in the preview, I assume because the template is split with several linebreaks. Same with Talk:Camouflage Nights. Talk:The Capitals uses the template without linebreaks, and the preview works. Cheers, BNutzer 19:28, 30 June 2007 (UTC)
• Crystalis - The second half of the introductory paragraph is cut off mid-sentence and replaced by the end of a sentence much later in the article, making a structurally sound but nonsensical statement. Amusing, perhaps, but it's not desirable overall. The issue seems to be caused by a self-closing reference tag, since output resumes just after the first standard </ref>. --AspiringSquire 18:18, 1 November 2007 (UTC)
• Midrash -- In Firefox 2.0.0.10 on Mac I see the following: "ImageSize = width:590 height:120 PlotArea = width:570 height:25 left:5 bottom:60 TimeAxis = orientation:horizontal DateFormat = yyyy Period = from:-250 till:2000 AlignBars = early ScaleMajor = unit:year increment:200 start:-200 ScaleMinor = unit:year increment:50 start:-200" Joriki (talk) 16:47, 27 December 2007 (UTC)
• Sanhedrin -- In Firefox 2.0.0.10 on Mac I get "A Sanhedrin ( ; ,". Joriki (talk) 13:16, 29 December 2007 (UTC)

  I think that’s because Popups ignores templates. What should be there is some Hebrew and Greek text, both of which is inside ((lang-he)) and ((lang-el)), respectively. — H92 (t · c · no) 20:26, 16 March 2008 (UTC)

• Offer and acceptance#Acceptance -- In Firefox 2.0.0.10 on Mac I get a box titled "Acceptance" with no further content. However, the preview for Offer and acceptance#Offer looks fine. Joriki (talk) 13:16, 29 December 2007 (UTC)
• Puppet state -- In Firefox 2.0.0.10 on Mac I get "A puppet state is a state". The article contains three reference footnotes in a row after that. Joriki (talk) 20:26, 4 January 2008 (UTC)
• Muslim Agricultural Revolution -- In Firefox 2.0.0.11 on Mac I get "The Islamic Golden Age from the 8th century to the 13th century witnessed a fundamental transformation in agriculture known as the Arab Agricultural Revolution, These introductions, along with ..." -- everything between "Arab Agricultural Revolution and "These introductions" is missing. Joriki (talk) 09:15, 13 January 2008 (UTC)
• Tokyo International Forum -- preview lists all the parameters of the first image, apparently because it starts with File: and not with Image:. AxelBoldt (talk) 18:13, 11 January 2009 (UTC)
• User:Frietjes' popup is currently unworkably long. It Is Me Here ^{t / c} 14:31, 4 February 2014 (UTC)
• Caldas da Rainha and Azores – Only the first image (in infobox) displays; no text from lead. I suspect the long infoboxes are the cause. —Nelson Ricardo (talk) 02:36, 7 May 2014 (UTC)
• VY Canis Majoris -- The intro text uses this template ((convert|1420|solar radius|km au|lk=on)) for the radius of the star, which should render like: 1,420 solar radii (990,000,000 km; 6.6 au). And uses this template ((convert|1.2|kpc|ly|abbr=off|lk=in)) for the distance to Earth, which should render like this: 1.2 kiloparsecs (3,900 light-years). But in the preview both of these render as an empty string. The rest of the preview looks fine. -- netjeff (talk) 21:55, 25 November 2017 (UTC)

FYI, I tried the window.popupPreviewKillTemplates = false; in my own user JavaScript file, but then the entire preview gets rendered as only ((Use dmy dates|date=September 2012)) ((Starbox end)), which is much worse. Is there a setting to skip over initial templates, and then after that to render the templates past that point as raw wiki? I guess handling templates in previews is hard. ☺️ -- netjeff (talk) 22:08, 25 November 2017 (UTC)

Should work now

Tennessee Williams - triple ] confuses Previewmaker

• Escherichia coli - ideally, close brackets or treat brackets as one sentence
• Dixie (song) (today's Main Page featured article) - reference markers should be stripped from the preview. e.g., "19th century,^[1]" previews as: "19th century,Nathan 248.". altmany 17:32, 31 January 2006 (UTC)
• Carolina Kostner and Tugba Karademir- both (perhaps others as well) display only )) rather than intro text. Seems to be picking up on )) at end of infobox. Note: I'm using IE, so it's possible (likely?) it's just a bug with this browser. EWS23 | (Leave me a message!) 04:56, 14 February 2006 (UTC)

Nope - also a problem in FF 1.5 altmany 06:33, 14 February 2006 (UTC)

• Live & Kicking, seems to choke on the ampresand. --AySz88^-^ 22:29, 23 January 2006 (UTC)
• I, D'oh-Bot - previews as: Error /**/ /**/

Prolly just overloaded servers?

• Drooling (with template-killing off)
• Ulnar nerve - just shows a | instead of content
• Israel Defense Forces - the 1st & 2nd images are located in a table ( ((Template:IDFTable)) ) and are skipped - the image displayed is actually the third, which is less relevant. I assume this happens with all similar pages.

Yes, the image shown in the popup is the first image in the raw wikitext, not the first image on the page. Changing that behaviour would be hard and make things slow, so I'm not going to do so. Lupin|talk|popups 19:11, 25 November 2005 (UTC)

• Special:Log and all other Special: pages
  • This works for me - popups are disabled for links to most special pages (as they should be, in my opinion, since you can't edit them or do much to them). Would you like to see previews generated for Special pages too? Lupin|talk|popups 12:08, 26 October 2005 (UTC)
    • I think most of the "&title=Foo&action=blah" links are having similar behaviour - showing the CSS of the target page as the popup text. Alphax ^τεχ 22:57, 1 November 2005 (UTC)

Hm, these seem to work for me. Maybe something changed, I forget! historyedit raw Lupin|talk|popups 19:11, 25 November 2005 (UTC)

• Japanese bobtail - redirect code doesn't like pipes
• Malaysia
• The Book of the Courtier
• University of Wisconsin-Madison
• Tamil language - removing ^| lines is a bad idea.
• Template:Opentask - has a link to itself with the words tasks you can do the popup displays unformatted wikitext. You can see this template in action on the Community_Portal Dalf | Talk 04:37, 22 November 2005 (UTC)

Yes, templates are shown "raw". This was added to fulfill a feature request, so I don't consider it to be a bug. Lupin|talk|popups 19:11, 25 November 2005 (UTC)

• Aluminium - previews as simply "x" – ABCD^e✉ 18:47, 3 December 2005 (UTC)
• Francois I of France,Francis I of France - now works, for some reason. BTW, that was a funny edit :) Zocky 12:43, 16 December 2005 (UTC)
• Procyonidae - don't break sentences on initials (with popupPreviewFirstParOnly=false)
• User:PuckSmith - Skips over everything down to the section 2. I'm getting the same results with Firefox 1.5, Opera 8.5 and IE 6. I'm currently looking at the source code both on the Wiki side and how my browsers are seeing it.--◀Puck^talk▶ 13:53, 11 January 2006 (UTC)

It was caused by way too many divs and tables at the start of the page. Works great now.--◀Puck^talk▶ 13:28, 14 January 2006 (UTC)

• Ichthys - what should we do with SVG images?
• Heroin now fixed - was caused by pairing {| with <table>
• Isis (h2/h3/par should get either all of that or h3/par; it just gets h3)
• Japan (italic intro text included)
  • Now fixed in article source - the "—" was out of italics. Maybe paragraphs that include nothing but italicised text and/or interpunction should be excluded.
• Jelly fungi - taxobox detection needs refinement (ignore "taxobox begin/end placement" templates)
• User_talk:Lupin - my oh my. this is odd.
• Kingdom of Ireland - multiple italic indented paragraphs, which some non-italic and bold bits
• Singer (2 pars? why?)
• SGR - uses TLAdisambig, but not recognized as a disambig
• Transformer gives a table fragment
• England, Wales (table problems)
• Roe v. Wade small, problematic table
• User:Dbenbenn - image tag with square brackets
• American English - over-zealous pruning of italic pages
• Raja Yoga - doubtless another italics-induced calamity
• Osiris - maybe the italics hacks should come after html tag removal
• Politics
• Philosophy - looks like section headings needn't begin lines. or something
• 1968 in film - should kill divs
• Satan - i.e. is not a sentence ending. i.?e.|e.?g.|n.?b.|sic.|etc.| any more?
• United Kingdom
• Goat - taxobox :-( fix idea: delete blocks of lines
• that won't work - eg Deer. just do a special taxobox case (yuck)
• Mohammad Reza Shah Pahlavi
• Alexander the Great (livepreview bug? not sure) '''((template))''' is a problem. hm. could replace templates with spaces instead of deleting?
• Genetically modified food - blank. category tag gets in the way - delete not just images, but also category "links"
• Cult figure (linkus interruptus) - Dr., Mr. Mrs. Ms. don't usually end sentences
• David R. Hawkins Shows as a single '}' character. It's presumably confused by beginning with:

<div class="messagebox cleanup metadata">This article or section '''is not written in the formal tone expected of an encyclopedia article'''.<br /><span style="font-size:90%">Please improve it or discuss changes on the [[((TALKPAGENAME))|talk page]]. See Wikipedia's [[Wikipedia:Guide to writing better articles|guide to writing better articles]] for suggestions.</span></div>(({category|))}

Thanks for the bug and diagnosis - this should now work in the dev version. Lupin|talk|popups 23:24, 14 December 2006 (UTC)

• Whip Jones shows similar behaviour, haven't looked into why. Josh Parris#: 00:18, 21 December 2006 (UTC)
• Carnegie Mellon University - the second paragraph is being previewed rather than the first. Thryduulf 08:53, 7 March 2006 (UTC)
• Union Jack - the first section is previewed, rather than the start of the article. -- Mithent 20:57, 20 April 2006 (UTC)

  First paragraph now. I assume that the hatnote isn't meant to preview. Josh Parris#: 03:19, 9 January 2007 (UTC)

• Sky+ history page Sky+ history page II - When previewing the history page, the popup gives a list of changes of the article Sky (cf Sky history page), omitting the +. Also, trying to preview an individual edit of Sky+, the popup gives "Empty revision, maybe non-existent" for both before and after. AthlonBoy 13:52, 1 June 2006 (UTC)

Which browser are you using? This works correctly in firefox. Nope, there is a problem with the history page... Lupin|talk|popups 14:13, 1 June 2006 (UTC)

Thanks for the report - this should be fixed in the dev version. Lupin|talk|popups 02:48, 2 June 2006 (UTC)

• Probably (South Park) - cuts off the question mark at the end of the link to "Do the Handicapped Go to Hell?"
