nightbre, I have installed is about 5-10 SMF for test purposes on different accounts(under Cpanel) on my dedicated server - I'm trying to convert my big forum.
And on all of them exit problem with session.
And it looks the same, like sesasso's problem.
I try to login on any of this SMF - ok. But I can't logout or go to the admin part, I got message
"Session verification failed. Please try logging out and back in again, and then try again."
Last month all scripts working well, but few days ago... such problem appear.
As I know(as dedicated server owner) - no changes was in PHP.ini, moreover, no any upgrades...or other.
So, for me it looks strange why such problem appear.
Becasue this problem appear on all installed SMF and affected on all new runned scripts as I show in my topic... it looks that problem is with server settings, PHP settings.
My first guess was that PHP can't access rights to directory session.save_path. But with this all ok.
I have session.save_path=/tmp
Delete then re-install all SMF is not correct way :-) I guess problem is with settings, PHP-settings. But what settings???
