Working on a project, for whatever reason one of the pages I’m reading up on doesn’t load the math formulas, instead showing error messages. Frankly it’s annoying, as they were literally displaying perfectly fine the other day. Any help on this? Searching the internet brings up nothing useful.
Edit: This was on firefox. Checked it on my phone’s firefox and chrome browsers and it still shows the error. This is probably on Wikipedia’s side of things.
You can click the edit or view source link and try to figure out what it’s supposed to say from there. This is certainly an error on the Wikimedia Foundation servers’ side. There used to be IRC channels where you could make the sysadmins aware of problems like this, not sure those still exist.
Can you link the article so that others can take a look?
Ok yep, I have the display issue as well. Interestingly, it only affects some of the equations. I’ll take a better look this evening
Also getting the same errors on mobile
This reference to localhost seems odd to me
The Wikimedia Foundation server’s “localhost”, i.e. the computer the wiki software is running from. That does make sense.
Well. What I find odd about it is that if there is reference to localhost then a production page is reaching out to clients computers to parse some math formula. I think the developer hardcoded something that worked for him and pushed to prod. It could possibly still work for him but not for others without a program listening on that port.
Possibly a broken adblocker
Probably a transient error. Have you tried clearing your browser cache and refreshing the page? (Usually Ctrl+R or Ctrl+F5; dunno about Macs)
It’s happening on multiple people’s devices, seemingly only the same equations.
Is it possible wiki caches the rendered latex on some event like page edits saved, ran into an error during that, and is now serving the errors from a cache?
Otherwise there must be an issue with these specific equations?
Seems plausible. When you edit the page and render a preview without changing anything, the formulas render correctly.
Didn’t work :/
The server sending over the plugin that can read MathML code is possibly down. Perhaps try again later?
