Hi!

We're using moodle version 1.9.8 and mimetex (compiled for Solaris), php 5.3.2.

We have two moodle systems one is for testing and the other is the production system.

At the prod. system the tex filtering works fine, but at the testing system not at all. We copied the content of filter/tex of the prod. system to the testing system. The course using the tex filter was copied to the testing system too.

But the math functions e.g.* $$ \sqrt{{a+b}\over{a-b}}$$* aren't displayed on the testingsystem through moodle but running mimetex with the math function shows the correct expression

. The moodle testing system shows \sqrt{{a+b}\over{a-b}} .

What is going wrong, that the expressions aren't shown on the testing system but on the prod. system?

Cheers,

Monica
