# [SOLVED]MathJax does not render any more

When I load a page - any page - the formulas do not render any more.
Normal text is there.
The unformatted Latex does show up for a fraction of a second in gray.
Normally this is followed by a replacement by formatted Latex, but now the unformatted Latex just disappears.

It appears MathJax has broken somehow.
I checked with 2 different browsers (Chrome and Firefox) on Windows.
Clearing cache and cookies does not help.

However, I do still get formulas on my Android mobile device.

Seconded. I'm using Firefox on Xubuntu 16.04.3 LTS 64 bit.

I am trying to investigate this issue, but the AdminCP keeps reloading every 5 seconds or so, preventing me from using it.

For what it's worth, everything is working correctly on my local dev site.

Jameson,

A search at vBcom for the issue I reported regarding the AdminCP suggests this could be a CloudFlare issue, specifically with Rocket Loader™. Can you switch this off?

Here is the post I found:

Blank for me too

Same here ...

When I save this page locally, and load it from there, it fails to render as well.

When I change the line:
Code:
<script type="text/rocketscript" data-rocketsrc="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js?config=TeX-AMS-MML_HTMLorMML-full"></script>
into:
Code:
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js?config=TeX-AMS-MML_HTMLorMML-full"></script>
the formula that skeeter posted renders correctly again.

So it seems there is something wrong with Cloudflare's rocketscript.
Can we disable it as MarkFL already suggested?
Or can we otherwise apply a quickfix as my change seems to suggest should be possible?

Ok it should be working now. I found a setting in CloudFlare that attempts to speed up your site through javascript manipulation and it was moving the MathJax script somewhere incorrectly. Please let me know if it's working now.
