I have been having an intermitant problem.
When adding comments to an assignment (using IE and win XP with moodle 2.1) after pressing save
1. I get kicked to login screen
2. after loging back in I get "A required parameter was missing
3. pressing continue twice returns me to my main moodle screen
This repeats after each "save"
Does not seem to be a problem with Netscape, and corrected itself yesterday but has returned this am.
All other features seem to be ok.
