Forum Errors After Upgrading 3.8x to 4.0.5
 

I just upgraded my forum from 3.8.x to 4.0.5

I get the following errors when trying to access my forum:

Warning: fetch_template() calls should be replaced by the vB_Template class. Template name: welcome_headers in [path]/includes/functions.php on line 3984

Fatal error: Call to a member function hide_errors() on a non-object in /home/shopped/public_html/forum/includes/class_bootstrap.php(394) : eval()'d code on line 43
