I've gone through some of this recently, so here's what I remember.
- you have to have dvipng installed, in addition to LaTex - if texvc is not run you see a red box telling you so where you'd normally expect math equations to appear. - by default Math.php runs ./math/texvc. You've to make sure that that file exists and is executable (and works). alternatively you can set $wgTexvc to the path of your system installed texvc - and of course you have to set $wgUseTex to true
I think the above was all I had to do for having math on my hosted wiki. In my case the problem was that the texvc I was uploaded was compiled for 64bit, while my shared server is a 32 bit machine, so even though the executable was there in the right place it was not that helpful.

Hi Dan,
This is most likely what is covered in the readme file. Read the
troubleshooting section, you need to install AMS.

I had tried following the trouble shooting suggestions... As far as I can tell, everything should work. I have a full LaTeX installation, since that's what I normally use to typeset my papers. I can run texvc correctly as the web server's user, it can read and write from /var/www/html/wiki/math and /var/www/html/wiki/images/tmp. I've even tried to follow the "hacking" suggestions to see if I could figure it out, but to no avail... Although I have noticed that when I run texvc by hand it creates the aux, tex, etc... files (I've commented out the deletion part of render.ml) and when it's run through wikimedia it doesn't. My guess is that it isn't even calling texvc...
Does any of the more experienced users have any suggestions? Thank you!

Dear All,
I've just finished installing mediawiki. Everything went fine, except
for
the TeX configuration... I've successfully compiled texvc and it runs correctly from the command line. However, typing
<math>\sqrt{n}</math>
in a post, results in:
*Failed to parse (unknown error): \sqrt{n}*** I've set $wgTexvc, $wgUseTeX and $wgEnableUploads. Am I missing
something?
Sincerely,
Bruno
