[Plugin: WordPress Social Login] Problem with LinkedIn login

I’m trying to use your plugin combined with “WP require auth” so the user has to login to see any page of the website. However, I can’t make it work with LinkedIn.
Once the website loads, it goes to the login screen, that’s fine. As soon as I click on the linkedin button, it goes to the “Contacting linkedin, please wait” screen and a few seconds later goes straight back to the website login screen. But it also adds a loop address to the address bar, and if I keep clicking on the Linkedin button, it keeps re-appending the redirect link on the address. Any idea how to make it work properly?
