In my Linux server, I can't login to my PHP application having an issue related to PHP sessions:

Everything was fine, no changes done in the server or application lately. I thought the tmp folder is corrupted and tried to change php session.save_path to other writable dir, but it did not help.
Thanks in advance for any help or direction.
