Unfortunately it can be a bit tricky to diagnose problems in the chain of events that is texvc, but once you've checked all these it should either be working or give some kind of error message. :)

Thank you. I have uncommented the line to enable TeX processing, put texvc into the math subdirectory, and changed the permissions on texvc and the images subdirectory. It doesn't work yet, but I am now getting an error message:
"Failed to parse (PNG conversion failed; check for correct installation of latex, dvips, gs, and convert): \sin x + \ln y \alpha a^2"

What do you suggest I do next?
