Upgraded from 1.5.1.3.1

Upgraded from 1.5.1.3.1 (fresh install) to 1.5.2.1, steps from 1 to 7 with no problem (upgrade.txt file), also config.php backup. Didn't try to upgrade from 1.5.2 to 1.5.2.1 yet...

After upgrade successfull message, customer shop is ok, but when i try to login on admin it brings me again to admin login, if i fail on password it tells me it's not ok (and reset password if i wanna), but can't accés admin page in any way. Login seems to be ok, but showns login page every time.

allready deleted all cookies on browser, also tried on different computer, and same result. Can't access to admin page, after login it brings again same screen to put username and password.

EDIT: sry, but didn't noticed before, there's also some PHP error;

Fatal error: Call to a member function get() on a non-object in /pathtoshop/opencart/admin/index.php on line 78

Sounds like the index.php file in admin is very wrong. There is no "get" call on line 78 of the admin index.php

Allready found the solution, it's godaddy hosting "bug" again, after changing session.php everything is OK
