I just ha a really strange problem:
Students in our computer classroom had problems seeing their own and other group members posts in group forums. Some of them also lacked the New post- button.
We tried every kind of reload of the pages.
I could see everything, and when I logged in as them (the students with problems) on my computer, everything worked just fine for each and every one.
Also, when the students with the described problems borrowed my computer and "really" logged in as themselves, everything worked just fine.
So, this problem seemed to be computer related!
Any suggestions, anyone?
(I'm using Moodle 1.6.3)
