I login to the admin facility to add users. After filling in the form and pressing Save, the login form pops up again. No error message. This happens most of the time, but not 100% of the time. When I log in again, he new user has not been added, and I have to enter the person again. When I refresh the browser (F5) before each addition, it works better. What could be happening here? Thanks. let me know if you need more information.
