I am experiencing some difficulties getting the tex filter to run. I have tried reading through some of the similar posts here but cannot see anything abvious to me. I have Moodle 1.9 running, hosted on a shared linux server. I ran the debug program with the following results.
1. See the cache_filters database entry for this expression (if any).
DB cache_filters entry for f(x)=\\Bigint_{-\\infty}^x~e^{-t^2}dt not found
3. Show a graphic image of the algebraic expression rendered with mimetex.

The shell command

4. Show a graphic image of the algebraic expression rendered with Tex/Ghostscript
A 'broken link' image is displayed - rectangle(s) with red cross in the middle
5. Show command execution output from the algebraic expression rendered with Tex/Ghostscript.
