I am trying to update from 1.5.7 to 1.6.6 and after running update.php I am getting the following message
A database error has occurred
Query: INSERT INTO `en_text` (old_id,old_text,old_flags) VALUES (NULL,'[[$1]] moved to [[$2]]','utf-8')
Function: Revision::insertOn
Error: 1048 Column 'old_id' cannot be null (localhost)
I know zero about mysql and can find nothing out there to help me.
Any ideas please
