I have set up a glossary and when I, the site admin, clicks on a word that is linked to the glossary, a small box pops up with the word and definition in it. This is how the Glossary Module should work.
A problem arises when a student does the same thing. In the box they get a synax error message which I've attached.
Sometimes they even get a blank page with the following message on it:
Coding error detected, it must be fixed by a programmer; PHP catachable fatal error.
Why does it work fine for me, teacher and site admin but not for the students?
