Hello!

I am new to phabricator so forgive me is this is posted in the wrong place. I have recently inherited a mediawiki server and I am learning the ins - outs of how to admin it. I was able to upgrade to the 1.34 version, I use bitnami to get the whole stack. One of my users requested the Math extension be installed, but I am not able to get it working properly. Looking at the special page for math shows an error saying TeX input is invalid. (See screenshot)

I took a peak at a previous phabricator issue here https://phabricator.wikimedia.org/T192447 but the fix did not work for me. Any insight that could be provided would be greatly appreciated, thank you for your time!
