I've just installed a clean PhpBB 2.0.19 from the tar.gz archive (Extracted through SSH.)
Installation went fine and without any errors.
But now,When I'm attempting to login,It's just redirecting to index.php without any error messages or something.
I've even tried to register a new account and login again but to no avail.
Server's Information :
Apache 1.3.34 (If that's matters.)
PHP Safe-Mode is turned off.
I've installed PhpBB 2.0.18 a while ago on the same server and everything is working fine with it.
Thanks in advance and happy new year to everyone.
