I'm sorry Daniel, idk what is the source of your problem. I do read compiled latex without problems.
Anyways some other sites gave me problems sometimes and I used this trick.
Take this link
Code:
javascript:(function(){if(window.MathJax===undefined){var%20script%20=%20document.createElement(%22script%22);script.type%20=%20%22text/javascript%22;script.src%20=%20%22https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js?config=TeX-AMS_HTML%22;var%20config%20=%20%27MathJax.Hub.Config({%27%20+%20%27extensions:%20[%22tex2jax.js%22],%27%20+%20%27tex2jax:%20{%20inlineMath:%20[[%22$%22,%22$%22],[%22\\\\\\\\\\\\(%22,%22\\\\\\\\\\\\)%22]],%20displayMath:%20[[%22$$%22,%22$$%22],[%22\\\\[%22,%22\\\\]%22]],%20processEscapes:%20true%20},%27%20+%20%27jax:%20[%22input/TeX%22,%22output/HTML-CSS%22]%27%20+%20%27});%27%20+%20%27MathJax.Hub.Startup.onload();%27;if%20(window.opera)%20{script.innerHTML%20=%20config}%20else%20{script.text%20=%20config}%20document.getElementsByTagName(%22head%22)[0].appendChild(script);(doChatJax=function(){window.setTimeout(doChatJax,1000);MathJax.Hub.Queue([%22Typeset%22,MathJax.Hub]);})();}else{MathJax.Hub.Queue([%22Typeset%22,MathJax.Hub]);}})();
and odd it to you bookmarks bar
Whenever in some site, mathjax does not render, hit the bookmark you've created. It should fix the problem
Source: I originally got this link in the MathStackExchange chat help section many years ago. Maybe it will fix your problems.
