Istalled but doesn’t see the fangate, can you help? What is the facebook app id?
To work properly you have to create a facebook app here https://developers.facebook.com/apps The facebook app should be configured to talk with your site, so remember to add your website URL in the FB app you created for SDK. Go to your fb App >> Settings >> +Add Platform >> Site URL, then save changes. That will make your modal work right away.
