MySQL Error

[cybtec]

I just completed upgrading from V3 to V 4.3.7 and all is well except for a small MySQL error.

I get the following when I log out of the Admin area.

MySQL Error Occurred

Error Message:

1048: Column 'sessIp' cannot be null

SQL:

UPDATE CubeCart_admin_users SET `sessId` = NULL,`sessIp` = NULL,`browser` = NULL WHERE sessId = 'faf49eb43ab0440dcddafbf4065ac9fc';

Doesn't anyone have a clue as to what the problem is and how to fix it.

Thanks
