Unable to login to migrated server
 

Dear all,

i've just moved my forum 3.8 from the old server to the new one.
Upload of files and database was ok, the only thing i have modified is the destination.

On the original server the forum was under /forum

while on the new one it's in the main directory, also because i want to upgrade to 4.x.

I have modified the forumpath in the includes/config.php and i'm able to see the new forum, but when i try to login ither as user or admin it recognized my user but it sends me back to login page.

What can i do?

Thanks,
