Can’t Load URL

this is probably configuration in facebook app settings. you need to add your website domain to some list there.

Having same problem and error. Definitely have domain listed correctly in app on Facebook. Double and triple checked it.

Checked in basic and advanced settings.

I’ve had this issue for over a year, tells me API error depreciated, so I just manually update the token every 2 months. Just debug your token, and extend here https://developers.facebook.com/tools/access_token/
