However, on entering some math content into the wiki and saving it, all i get is the following error message as output: Failed to parse (Can't write to or create math output directory)
Try using texvc on a command prompt; the README in the /math directory tells you how. I had similar problems, and I found out that I did not install TeX properly on my system. From the command line, texvc runs now, I haven't tried from within the wiki until now...
To exactly know what the problem is, you need the output from texvc, which is shown when you run it from the command prompt.
