Hi
After upgrading to vbulletin forum 4.1.1 this error appeared:

Fatal error: Call to a member function hide_errors() on a non-object in /home/***/public_html/test/includes/class_bootstrap.php(412) : eval()'d code on line 68

and when logging on to admincp:

Warning: fetch_template() calls should be replaced by the vB_Template class. Template name: cyb_tictactoe in [path]/includes/functions.php on line 4097

Fatal error: Call to a member function hide_errors() on a non-object in /home/***/public_html/test/includes/class_bootstrap.php(412) : eval()'d code on line 1161

tictactoe is a hack.. remove it and try again.
