Lately, the whole site has been frequently popping up error pages that start with "Sorry! This site is experiencing technical difficulties." followed by a whole bunch of error lines. This can occur when trying to do literally anything -- going to any page can do this (not even trying to post anything, although it happens when doing that as well). Is this a hosting provider problem, or anything that it is possible to do something about?

:: Yeah, this is an internet-wide problem caused by the insatiable hunger of the AI companies for stealing everyone's data to put in their training models. Multiple forums I'm on have also had their view counts go through the roof recently without a corresponding increase in actual posts and had to implement anti-bot measures. It's not going to get better until the AI bubble bursts. [[User:Yourmusic Productions|Yourmusic Productions]] ([[User talk:Yourmusic Productions|talk]]) 18:21, 10 September 2025 (UTC)

:::: I hadn't thought that far. However, I do think it makes sense to strictly regulate what can be brought to RecentChanges.

::::: On the one hand, we're already using CloudFlare for the "prove you're human" checkbox to combat the AI scrapers that were DDoS'ing the site in all but name. On the other hand, at least as of last night, the AI scrapers seem to have figured out how to get past that, because the very frequent "unable to access the database" errors started appearing again, so maybe different medicine is needed.

:::: That sounds plausible. Also, for what it's worth, [https://memory-alpha.fandom.com/wiki/Portal:Main '''Memory Alpha'''] uses the kind of Captcha that gives you semi-obfuscated letters/digits that you have to enter, and while that is even more annoying than the CloudFlare checkbox, so far I haven't run into database access failure on there.

:: On the page [[User:Overthink/Chords of pajara]], when I check the revision history only the oldest three revisions appear, and both a hard refresh and clearing my browser cache don't work.

:::: I made an edit to [[22edo]] a few minutes ago. Many recent edits don't show up in the edit history, and the to date filter reveals more, but still doesn't show my latest edit.

== HTTP 403 errors when previewing edits ==

When I use the auto-preview option in the source editor, sometimes it returns an HTTP 403 error instead of previewing the page. Previously, I opened/refreshed another xenwiki page and the cloudflare verification always showed up, and after it finished the edit preview box started working again. Now, refreshing another page doesn't show the verification message, and the preview still returns HTTP 403. Strangely, when I try to edit a different page, the preview section does show properly.--[[User:Overthink|Overthink]] ([[User talk:Overthink|talk]]) 03:36, 14 February 2026 (UTC)

== Errors when saving edits ==

I often get the error message:

Sorry! We could not process your edit due to a loss of session data.

You might have been logged out. Please verify that you're still logged in and try again. If it still does not work, try logging out and logging back in, and check that your browser allows cookies from this site.

</blockquote>

Usually it works after clicking "save changes" again, but it's still quite annoying. --[[User:Overthink|Overthink]] ([[User talk:Overthink|talk]]) 07:01, 25 February 2026 (UTC)

: I see the same thing. It occurs more often when I take a long time before previewing or saving changes, but occasionally it happens even in a short editing session. And while it usually works after saving changes again, occasionally it loses some or all of my changes. [[User:Lucius Chiaraviglio|Lucius Chiaraviglio]] ([[User talk:Lucius Chiaraviglio|talk]]) 11:05, 25 February 2026 (UTC)

:: Since I last posted, this has started happening frequently even in short editing sessions. [[User:Lucius Chiaraviglio|Lucius Chiaraviglio]] ([[User talk:Lucius Chiaraviglio|talk]]) 03:13, 21 March 2026 (UTC)

== Audio files from Wikimedia Commons ==

Why I try to add an audio file from Wikimedia Commons, it shows up as a link to the file instead. For example:

[[File:Primary triads in C just.mid]]

Please fix this issue. --[[User:Overthink|Overthink]] ([[User talk:Overthink|talk]]) 22:15, 20 March 2026 (UTC)

== Editing sections returns to wrong section ==

For example, if I edit an "11-limit" section in a temperament data page, after clicking "save changes", it puts me at the ''first'' section that says "11-limit", instead of the one I was editing. This is a relatively minor issue, but I still believe it is important to take note of this. --[[User:Overthink|Overthink]] ([[User talk:Overthink|talk]]) 01:29, 21 March 2026 (UTC)
