Having a bit of a problem with setting up new forums in a course. I can create the forum and post to it using one account.
Then I log in as another and click on the forum link and get the following
Must specify a course module or a forum ID
Wierd thing is, you reload the page a couple of times and then it works..until the next time...
Any ideas, is it a permission thing?
By any chance did you use the import function in moodle to import the forum into this course from another?
Sometimes the import function can cause this?
What version of moodle are you using?
