Forum blank page after upgrade
 

When I login to my admincp I get this error:

Warning: fetch_template() calls should be replaced by the vB_Template class. Template name: advertisement_leftcolumn in [path]/includes/functions.php on line 3932

Warning: Cannot modify header information - headers already sent by (output started at [path]/includes/class_core.php:4482) in [path]/madp/detection.php on line 299


It must be hack related (madp) so how can I uninstall all hacks and redo the install procedure?
