Hi
I have the latest version of SLF (version 1.0.1.4), I have a Facebook account for only this app.
Followed the instructions, setup the app, entered App ID and App secret into SLF.
Whilst logged into the FB account where the app was created I try to connect via SLF.
I too get the message "Given URL is not permitted by the application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains."
Any clues?
