Didn’t know about this one, but if you’re having a problem where the FB login buttons added by SFC don’t seem to do anything, try this:
- Go to https://developers.facebook.com/apps/ and click on the App in question.
- In the left menu, under Settings, click Advanced and look at the settings in the Migrations section.
- Switch the “Encrypted Access Token” setting to ‘Enabled’.
Might fix the issue.
