Facebook API since October 1st, 2018 requires a mandatory App ID in order to continue using their Share/Recommend buttons events (essential to allow Social Share meet when an user performs those actions).

3. Pass the security check if required and click on Submit:

4. Click Settings -> Basic in the menu at the left:

5. Twice enter your site domain name (without “www” and with “www” if your are using this subdomain), check your email address, select the category and paste links to Terms & Policy pages:

6. Fill the form Data Protection Officer Contact Information below if required according to your business:

7. Click on Add Platform after the forms:

8. Select Website:

9. Specify an URL of your website and save the changes:

10. Move to the section App Review:

11. Make your app available to the general public:

12. Copy your app ID:

13. Paste your Facebook App ID on the page GamiPress -> Settings -> Add-ons -> Social Share -> Facebook.

That’s all! Now Social Share will use your Facebook App ID to load the facebook buttons.
