First off : thanks for your work on this plugin.
Has been working good up till now.
When I try to login through Facebook the process becomes unbareably slow. (and it didn't used to be like that).
As I'm still developing the site, surely I have added a lot of stuff, but I'm not sure if/that I added stuff that would mess up the login procedure.
I've checked with Chrome dev tools and noticed that the process is "hanging" on my wp-login.php page ... (takes 16 seconds) ...
When I login "normally" , with my WordPress username/password combo it's as fast as ever.
Just through the Facebook login , it becomes slow again.
I've added a screenshot of the "firebug" status of the page that is causing the slowness:
edit : done some more research.
This page : http://www.mysite.com/site/wp-content/plugins/wordpress-social-login/services/authenticate.php?provider=Facebook
is taking 10seconds (almost consistently) to pass through ...
edit 2: did a fresh WP install on the same server - installed WordPress Social login and have the exact same issue.... takes 10 or more secs to authenticate through FB.
I'm starting to suspect this is a server issue. (altho it worked fine before)
