In my web console I see:
Code: [Select]
Loading failed for the <script> with source “https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=default,Safe”.
This CDN has been deprecated for a long time, maybe it finally got turned off?
navigating to the URL gives me an error in Firefox:
Code: [Select]
Content Encoding Error
An error occurred during a connection to cdn.mathjax.org.
Please contact the website owners to inform them of this problem.

in the page source (generated by whatever forum plugin) this line
Code: [Select]
<script type="text/javascript" src="//cdn.mathjax.org/mathjax/latest/MathJax.js?config=default,Safe"></script>should probably be replace by this line
Code: [Select]
<script src='https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/latest.js?config=TeX-MML-AM_CHTML' async></script>as per https://www.mathjax.org/#gettingstarted

or you could have a local MathJax installation served from the fractalforums.org server if you don't like cloudflare.

I see this (attached) in my browser...

ping cdn.mathjax.org returns appropriate response...

browsing the site in FireFox shows XML (correct error when browsed directly?)
Code: [Select]
<Error>
  <Code>AccessDenied</Code>
    <Message>Access denied.</Message>
      <Details>Anonymous caller does not have storage.objects.list access to cdn.mathjax.org.</Details>
</Error>

I think the site is still up and working but thanks for the heads up, I will modify the MathJax references when I have time, there is no new version of the installed Mod yet :(
Resistance is fertile... you will be illuminated!

arrgh, sorry for wasting your time.  error was at my end.  works now.  wget got the file fine, so I dug a bit with the web developer console, saw that it was cached even though I thought I was forcing reloads with ctrl and shift refresh, also try again button loaded from cache (wtf).  no option to selectively clear items from the cache (wtf), so I nuked it (kept my cookies for nomnoms later) and it worked. firefox quantum 61.0.1 considered not so great, caching broken things is foolish...

 :)) not a waste of time! you are correct, cdn.mathjax.org is deprecated and the references should be updated to reflect this, FF uses cdn.mathjax.org/mathjax/latest/MathJax.js?config=default,Safe so it would be reasonable to assume that requesting "latest" from the deprecated server would forward the request to the new server and feed us the right file, big assumption but very likely, so, we will wait and see if the MathJax Mod gets updated, if not then a bit of digging into the mod source will reveal exactly where things need to be changed to bring it up to date.  :thumbs: thanks for pointing this out.
