Mea culpa

Cheatsheet for WikiElves (for lack of better title ideas) ... a file where I can list solutions for challenges met at the backlog and elsewhere.

CAT:MISSFILE

<nowiki>...</nowiki> tags
- Naples
- There was nothing wrong with any of the image files, yet the article was in CAT:MISSFILE. The problem was caused by some odd <nowiki>...</nowiki> tags, none of them properly opened and closed; removing them was the solution.
- Special:Diff/849999040/850001739
Link to Commons redirect
- Pop-up book
- Image File:Pop-Up Movable & Three Dimensional Books catalog.ogg showed as deleted, though there was no history of deletion in the Commons log. No one had edited the page since May 7, 2018, though the file did not show up in CAT:MISSFILE until two months later.

  - KatnissEverdeen: Here is what happened: Nicolet1327 (talk · contribs) uploaded the file on Commons as File:Pop-Up Movable & Three Dimensional Books catalog.ogg (per 19 July 2018 that page still exists on Commons for non-admins to view), and added that file name to Pop-up book in a series of edits starting in Special:Diff/821399457/839983039 just past midnight on 7 May. Later that day at 22:06 UTC over on Commons, "SteinsplitterBot moved page File:Pop-Up Movable & Three Dimensional Books catalog.ogg to File:Pop-Up Movable & Three Dimensional Books catalog.ogv: 6 (Non-controversial maintenance and bug fixes): MIME type mismatches file extension. https://www.ietf.org/rfc/rfc5334.txt" turning File:Pop-Up Movable & Three Dimensional Books catalog.ogg into a redirect. File:Pop-Up Movable & Three Dimensional Books catalog.ogv was nominated for deletion on 9 May, and was deleted on 18 July. Sam Sailor 07:42, 19 July 2018 (UTC)

WP:NOREFLIST

{{:List of Supernatural episodes}}
- Supernatural (U.S. TV series)
- A Cite error: There are <ref group=a> tags on this page, but the references will not show without a {{reflist|group=a}} template (see the help page). message was present, and I spent some time looking for unclosed ref tags, but could not see anything was wrong. The solution was to spot check the article history and find where the error first occured. It turned out to be the addition of {{:List of Supernatural episodes}} in Special:Diff/841123985/next that caused it, I've never seen that before, and when removed in Special:Diff/849970482 things were back to normal and no cite error was reported.
