 * Hello everyone,
 * I’ve just started using wpcatalogue plugin & it’s been great for the past couple
   of days, but today when I was browsing through the product pages I got an error
   which read “Fatal error: Call to undefined function is_product_category() in /
   home/carbon/public_html/wp-content/themes/industrial/header.php on line 416”
 * Before I posted this I tried deactivating the plugin and reactivating it, I tried
   to reset the slug to default as per the instructions given on this post [http://wordpress.org/support/topic/change-for-sef-url?replies=6](http://wordpress.org/support/topic/change-for-sef-url?replies=6)
 * All my product pages are down and I have no clue on how to fix this. please help.
   My product page link is [http://www.carbonbrush.co.in/productcatalog/tool-cabinet-trolleys/](http://www.carbonbrush.co.in/productcatalog/tool-cabinet-trolleys/)
 * Regards
    Murtaza
