Hi Alex,
It appears as if this part cannot be bypassed in Facebook set up.
In Facebook App security settings (for login button) it requests: "Server IP Whitelist - Make sure this whitelist is set so API calls can only originate from IP addresses you trust.
"
Then goes to page with field for :
"Server IP Whitelist"
and
"Update Settings IP Whitelist"
Would this be referring to the IP from which my site originates, eg my static IP at my ISP?
Regards,
Nev
