TeX Live and MacTeX ⇒ No output in moodle

[astarmathsandphysics]

I installed livetex on ubuntu 12.04 to use with moodle.
Where I would expect an equation I get the latex code.
In debuggin mode click in the code gives the following information:

I think the 'not writable' messages probably means not there, since I have looked for those files to investigate permissions and can't find them.

How can I solve this?

Welcome to the forum!

convert is a command line tool of ImageMagick, I think you need to install it via the Ubuntu package manager.

Also the package dvisvgm needs to be installed.
