I would like to implement banners of facebook into my web HTML. the guide i worked with is: https://developers.facebook.com/docs/audience-network/mobileweb/javascript i did everythig good. but the banner is not showing in my web html. what can go wrong? (i pressed the "GET HTML" from placement tag and put it with the right "placementid" and "app_id"...
(p.s) i implement the mobile android guide and it worked very good, only the web makes trouble.
