I have problems with the Math extension on my wiki ecoepi.shoutwiki.com
Math is working correctly for me on your hub wiki, and some other shoutwikis I tested. On ecoepi, I can't save any page containing a <math> tag, no matter how my setting for math rendering are in the preferences.
I can't preview math at all with setting "MathML with SVG or PNG fallback".
Preview with "PNG images" gives an error message on the page:
"Failed to parse (PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)): a^b"
Preview with "LaTeX source (for text browsers)" works, but saving not.
