I used to have this problem before upgrading and thought it was just a fluke that all the sudden started happening. I upgraded to the latest Coppermine version and also updated my forums from SE to SMF. Everything works fine and I no longer have the logout problem... with one exception. I've come to find out in testing that this only happens with certain templates. More particularly, the SMF template of CPG that I want to use. How come this problem is specific to templates? How can I adjust the SMF CPG template to allow users to logout correctly?
please provide a link and test account so we can check this. I've never heard of a theme being responsible for session issues... Please understand that the SMF theme is a user contribution, we can not fully support it.
