Recently our Moodle has given us some problems related to sessions timing out.
Sometimes when a user logs on, they are unable to and get the message that the session has timed out even though they havent managed to logon.
Or, when they are working on it, suddenly when they click on anything it becomes obvious that they have been logged out.
The server is set to the maximum time allows - 2 hours I think
I don't know much about Moodle, can anyone give me any pointers?
We upgraded to 2.2 at Christmas and it has been fine until now. Nothing else has changed.
