First of all sorry for the long subject title. But the problem is exactly like I said: 2 of our teachers have a strange problem:
when they move an item in the course list with AJAX, the item seems to be moved. But after a page refresh, it is back in the old place. I can't figure out where the problem is.
AJAX is enabled for the whole site, as well as in the users' accounts. Teachers have standard roles of editing techers. It is not a matter of hardware - the teachers ahve the same problem on other computers as well. If I (the admin) log in as one of the teachers I can't move items either.
We use the latest 1.9 edition hosted on our own Ubuntu server.
Could anybody please give me a clue?
