Developer has abandoned this plugin. Cookie method for Premium API Facebook is seen as spam by facebook and will get your account shut down. (c_usr) & (xs or session) method is considered a hacked account!
Created multiple support tickets with ZERO response.
Plugin has not been updated in months with ZERO sign of life.
YET THE SALES SCREEN STILL WORKS!
DO NOT BUY THIS PLUGIN... ABSOLUTELY HORRIBLE PRODUCT!
