Hey,
Right, with this error:
Warning: Unknown: open(/var/php_sessions/sess_b82c70e5099744e7c2ecaf96d2f81658, O_RDWR) failed: No such file or directory (2) in Unknown on line 0
Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/php_sessions) in Unknown on
line 0
That has to goto your host, there's a server configuration error. Without that setting (that essentially means it can't save the login information), so you won't be able to make it into the admin panel or stay logged in. After that, there are instructions here:
