Steps to reproduce the issue

When adding a module to include a Facebook like display, it saves ok but when viewed on the page it comes up with "Error: Not a valid Facebook Page URL." - note that the link to Facebook is to a group name which works ok in a browser [the URL is https://www.facebook.com/groups/mandurahvolleyball/]

Expected result

Displays a rolling Facebook page on the front of mandurahvolleyball.com
This works ok with a Facebook page of the same name, i.e. Mandurahvolleyball... [the URL is https://www.facebook.com/Mandurah-Volleyball-Association-Inc-214292481923948/]

Actual result

Receive this message on the web page... Error: Not a valid Facebook Page URL.
