 * I just upgraded and I’m having couple issues.
    First is this which is killing
   me
 * Warning: array_walk_recursive() [function.array-walk-recursive]: The argument
   should be an array in /home1/vissius/public_html/wp-content/themes/vizio/sp-framework/

   php on line 896
 * and then the image zoom feature is not working too well after the upgrade. I’m
   not sure if it has something to do with the theme not being compatible or anything
   else.
 * I would appreciate any help possible. Thank You guys!!!

 * This is an issue with your Vizio theme and not with the WooCommerce plugin.
 * Please contact your theme developer for a solution.
