Can't update profile on frontend

I get this error when I try to update my first name field in CB.

moscomprofiler::store failed: Unknown column 'nickname' in 'field list' SQL=UPDATE `jos_comprofiler` SET `user_id`=66,`firstname`='Nathaniel',`middlename`='',`lastname`='',`hits`='0',`message_last_sent`='0000-00-00 00:00:00',`message_number_sent`='0',`avatar`='66_4e85082a1e76c.png',`avatarapproved`='1',`approved`=1,`confirmed`=1,`registeripaddr`='',`cbactivation`='',`banned`='0',`acceptedterms`='0',`nickname`='',`gender`='',`lastupdatedate`='2011-09-29 20:19:17' WHERE id='66'

I am new to CB

CB version 1.3.1
Joomla version 1.5.23

[mod note: moved out of bug area]

This is not a CB bug.

CB has no such nickname field.

Something else you installed is causing this.

Try running tools to see if it is fixed.
Find what is causing this and remove it.
Add a nickname column in comprofiler table could also fix this.

Upgrade to CB 1.7.
