[texhax] Formulas not rendering on site

[Jacob David Tafoya]

Hello,

I recently became the new IT Manager for one of the math departments at our university and inherited a MediaWiki site which uses TeX version 3.141592 (Web2C 7.5.6) on Red Hat 6.7. None of the formulas are rendering and instead show the HTML source, similar to this: <math>\frac{dT}{dt}=r_{2}T(1-bT)-\frac{aET}{g_{2}+T}</math>. I have no clue how long this issue has been going on. There have been no changes to this site apart from a faculty member adding to the MediaWiki page- no system changes have been done in many years.

I researched the issue for about 2 hours and can't really find a solid answer as to why the formulas aren't rendering. My first thought was to update TeX using tlmgr update -all but this cannot be done since tlmgr is not installed and I do not have root access to install it.

Can you please help?

Thanks,
Jacob T.
