# Variation Call Error

 * My product categories seem to be malfunctioning, and it is not isolated to any
   one. Some of them work fine and others do not when I like to them either via 
   the products page (grid view show categories) or with shortcodes. It seems fine
   in Chrome, randomly does not work in Firefox, and fails miserably in Safari.
 * I receive this error when using Firefox and Safari when I go to a Product Category
   Page:
 * Fatal error: Call to a member function have_variation_groups() on a non-object
   in /homepages/5/d199347309/htdocs/coffee/wp-content/plugins/wp-e-commerce/wpsc-
   includes/product-template.php on line 1397

 * Using latest plugin, wordpress, and Aggregate theme. Any help is appreciated.
   Also, if you could reference what files you would change if you know of the fix
   that would be appreciated.
