Hi, I was using moodle version 2.9 before and I decided to upgrade it because I was getting an error message like this "Incorrect sesskey submitted, form not accepted!".
After upgrading to 3.2, I still get the same error which every 5mins of trying to do one thing or the other on the site. I could not add new user, course or do anything without getting the error, so i decided to bring the site down and install afresh but the same problem still persist.
Can some please tell what to do?
