MEpedia:Known bugs

Citoid

 * 1) PMC or PMCPMC automatically generated citations - our Module code edited by User:Notjusttired to avoid this. Two related fixes fine recently by citoid haven't fixed all cases for us - User:Notjusttired
 * 2) Automatically generating dates sometimes gives a slash (/) in the date, normally the month number is also wrong. Eg 2019/6 example try using Convert here -
 * 3) Automatically generating dates sometimes gives a unrecognizable date format of YYYY-DD eg 2015-02 or 2005/06,, this gives 2005/06 error example as seen using convert here -

VisualEditor

 * 1) VisualEditor experiences significant slow-down on long pages, and sometimes appears to hang.  No fix is anticipated, but workaround instructions are here: MEpedia:Visual_editor

TemplateData/VisualEditor

 * 1) There is a known bug where TemplateData stored in a "/doc" subpage will not show up in the VisualEditor.  The simplest workaround is to store all TemplateData in the main template page, instead of in a "/doc" subpage.  Another suggested workaround is to do a null edit to the main template page every time the TemplateData is updated in the "/doc" subpage.

Page displayed with previous editor's preferences
Sometimes, a page will be displayed according to the preferences of the last person to edit the page. In this case, the "edit" and "edit source" section links in a page can show up in a foreign language, even when the page content is English and the reader's language preference is English. A page can also display link colors according to the previous editor's CSS settings. The fix is to clear the server's page cache for the page. To do this, add “&action=purge” to the end of the page’s URL and reload the page.

Cite.php (formerly known as the Cite extension)
Pages with problem or tags are identified by Cite.php and these errors show up in bright red on the page with the error. Pages with these errors are added to the category listing Category:Pages with reference errors. However, for some reason, some pages are included in this category even though they have no obvious errors. (e.g. File:CFS-UK-4.png, Category:Mental disorders) Therefore, anyone reviewing the page Category:Pages with reference errors should be aware that not all pages listed will necessarily have errors in them. (The exact location of the code that produces this bug is unknown.)

File upload at Special:Upload
When you upload a new version of an existing image, the old version will continue to be displayed for about 24 hours after uploading the new version. This makes it look like the new version is identical to the old version, leading people to believe that the upload of the new version failed, when it didn't.

Special:AllMessages
The Special:AllMessages page does not show any interface messages that we have created ourselves, such as MediaWiki:Pages in-need. (So much for "all" messages!)

Templates
[citation needed]
 * FIXED BY NJT 26 SEPT 2019. Citation needed: If a date is specified in a mainspace article, it displays:
 * This only occurs in the main namespace. If no date is specified, it shows up fine. For examples, see Hypothalamic-pituitary-adrenal_axis and De_Bortgjemte.


 * FIXED BY PYRRHUS 26 SEPT 2019 Citation needed: All pages marked with the "Citation needed" template have recently disappeared from Category:All articles with unsourced statements.
 * Citation needed: The tracking category Category:All articles with unsourced statements includes pages/files that do NOT have a "Citation needed" template. Sometimes a simple null edit will remove them from the category.  Sometimes not.  (The exact location of the code that produces this bug is unknown.)

Mobile issues affecting all skins

 * Alerts / notifications (echo feature) do not fit in the screen. Temporary CSS being used to improve this, which may need updating for each MediaWiki release notjusttired (talk) 05:53, July 21, 2019 (EDT)
