I have recently upgraded OJS to 3.1.1, I did not realize our server was running php 5.5 instead of 5.6, I changed the php version to 5.6 and now have this error DB Error: Duplicate entry ‘NULL’ for key ‘sessions_user_id’ and the sessions log has over 37000 entries, I turned off the session check ip in the config.inc.php file however this did not help.
