[Forum] error message after upgrade

[Stedman]

i just re-installed my board and i'm getting this message:

Warning: require_once([path]/mgc_cb_evo/classes/class_core.php) [function.require-once]: failed to open stream: No such file or directory in [path]/includes/class_bootstrap.php(95) : eval()'d code on line 4

Fatal error: require_once() [function.require]: Failed opening required '/home/thirdtie/public_html/forums/mgc_cb_evo/classes/class_core.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/thirdtie/public_html/forums/includes/class_bootstrap.php(95) : eval()'d code on line 4

i remember that i've gotten that problem before when i installed the first time but i wasn't able to find how it was resolved.

forum is located here: http://thirdtierboard.com/forums

thanks

That error is due to an add-on. You need to either remove the add-on causing this, or contact the author for assistance.
