If you refer to the edits I supplied. I did not change anything more than adding the ability to read the datastore properly and one phrase add. All other info is the authors.
Are you using table prefix?
Code:
FROM _vbvbs_ticket_post AS post
LEFT JOIN _vbuser AS user ON(user.userid = post.userid)
LEFT JOIN _vbuserfield AS userfield ON(userfield.userid = user.userid)
LEFT JOIN _vbusertextfield AS usertextfield ON(usertextfield.userid = user.userid)
The code should not look like that
