Hi, all, I have just upgraded mediawiki from 1.16.5 to 1.18.2. Everything works well except the math extension. When I try to display a page with math on it, I get the following error message:
Failed to parse (PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)): I've gone through the recommendations in http://www.mediawiki.org/wiki/Manual:Enable_TeX and http://www.mediawiki.org/wiki/Manual:Troubleshooting_math_display_errors without any success. Dvips, gs, and convert are all installed with permissions that enable the apache user to execute them, latex is installed (via texlive), and I even threw in the mathtex package, thinking that it sounded as if it must be useful without knowing whether it is actually used. Anybody have this working? Care to share how you did it, or suggest debugging techniques? Thanks, John Blinka
