From the time i bought this plugin years ago i always used it without woocommerce.
Now i changed to a new theme, and FPD stops working asking me to fix: woocommerce_cart_item_thumbnail filter is missing in the woocommerce templates of your theme
Wait... i don't use woocommerce, the wp theme does not use woocommerce also, i have no woocommerce folder in my theme...
Why FPD is asking for a filter that should not exist in the first place?!!!
