I don't know much about databases, I just installed osTocket and during the user account I get this message:
user_id= 8 ON DUPLICATE KEY UPDATE
Unknown column 'phone' in 'field list'<br />
I found a message to drop/delete table "os_user__cdata" but when I do this, the users do not work - can't log in.
What do I have to do to get rid of this error? This error appears from the beginning of a clean install.
