Cannot log in!!

[lloowen]

Hello!

I've just installed the latest Roundcube on my server and I cannot log in! I can log in for all of 3 seconds then I'm automatically logged out! Then after that I cannot log in at all unless I restart apache2 and mysql.

Looking at the error logs I get this:

Authentication failed. in /.../program/include/rcube_imap.php on line 183 (POST /?_task=login&_action=login)

I've tested my imap using telnet and it is working as it should.

I would be grateful for any help on how to solve this.
