First off, I have to point out I am using the laatest nightly build of 1.6!!
All my modules are working except for the glossary. Before the upgrade I had about 22 different glossaries on my website of various formats.
Since moving to 1.6 they have all stopped working. Whenever I go to one I always get taken to a Teacher-Defined Glossary. The url's are showing correct, but the content is listing the Teacher-Defined Glossary with the default content.
Also, should I try to edit any glossary, I get taken to "Updating forum in section 0". Both of these errors are extremely odd.
I have tried reverting back to my old 1.5.2 glossary but the error persists.
As a student, If they click on any glossary the error "Course Module ID was incorrect" appears.
I have also tried creating new glossaries from scrtach but the above always happens.
Is this a bug anyone is aware of?
Don't worry. (not that anyone was) 
Issue has been fixed
Yes, how? (I had flagged this in my TODO list) DB corruption?
Ciao

I just grabbed a new nightly build. looks like the issue has allready been rectified. My understanding is that this was a code, not DB issue.
