I have a project on Sourceforge that has a mediawiki (1.6.8), which is working well. I want to enable Math support for latex equations. It doesn't work, and I've read all the "it doesn't work pages"
Sourceforge does not allow the webserver to create images on the fly. I had a similar problem and ended up using mimetex: see http://meta.wikimedia.org/wiki/LaTex_on_a_shared_host or http://meta.wikimedia.org/wiki/Mimetex_alternative
