Product Feature Error

I checked the KB for help with the Product Feature and I tried to set it up the same way but it will not work as the feature is not displaying in the product List page at all and then I am now getting this error notice at the top of the product list and detailed page :

Warning: Illegal offset type in isset or empty in /home/goodlife/public_html/core/fn.catalog.php on line 3538

Can someone please help me with this error and why the product feature is not showing up on the catalog pages as the instructions said it will.


It might be a different issue, but I had the same error when I unchecked “Use the selected layout for current category or search page only” in Administration/Settings/Appearance. I hope I helped someone.:rolleyes:
