CMS Unknown column 'vbcmspermissions' in 'field list' error
 

I do not have CMS enabled. I keep it disabled. Yet I am seeing this error:

Code:
Invalid SQL:
SELECT vbcmspermissions FROM ibf_administrator WHERE userid = 1;

I tried removing the CMS product from the backend. The process crashes with this error:

Code:
Database error in vBulletin 4.2.0:

Invalid SQL:

ON cms_widgetconfig.widgetid = cms_widget.widgetid
WHERE package.productid = 'vbcms';
