    After the update to 2.0 I have the following error on the bottom of my page.

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘wpgs_product_lightbox’ not found or invalid function name in /home/latterda/public_html/wp-includes/class-wp-hook.php on line 286
