Urgent: Getting Database error resulting in site not functioning

[dhruv96]

Hello Everyone,

We are experience a critical error on our domain which presently has two types of general users:

1) Registered Users: Users who just want to chat
2) Premium Users: Individuals who get access to specifically enhanced data.

The problem is, users are able to successfully register and their registration information is created and stored, and is accessible via admincp. However, individuals who upgrade their package to a paid premium package are not getting promoted to the Premium Usergroup and instead remain Registered.

The problem here is when we go into admincp to make the change manually, we get this database error when we push save.

Database error in vBulletin 4.1.3:

Invalid SQL:
INSERT INTO userchangelog
	(userid, adminid, fieldname, oldvalue, newvalue, change_time, change_uniq, ipaddress)
VALUES
	('6423', '4809', 'usergroupid', '2', 9, 1306795519, '5b43c2172497106f441e182b661b0e77', 2904586262);

MySQL Error   : Unknown column 'ipaddress' in 'field list'
Error Number  : 1054

As the settings are CONFIRMED to be set up correctly regarding the promotion to Premium from Registered, this issue has something to do within the database of vbulletin script which I am seriously hoping some one may have come across a similar situation or there exists a patch or fix which can be applied towards fixing this.
