Problem upgrading to 3.3.0.4 from 3.2.1.1

Hi @hilongo, It sounds like you have some incomplete/invalid entries in your email_log table. Run the following query: select count(*) from email_log where assoc_id is null; This should indicate the problem rows. You may want to remove them (after restoring your database from backup, before running the upgrade script). Regards, Alec Smecher Public Knowledge Project Team
