Not working with LinkedIn

Hi. I instead this plugin as it looks like it had some great features. However, despite checking and rechecking all configurations, the LinkedIn social login doesn’t work.

The OAUTH is accepted, but then just returns to the login screen and if you then attempt to use wp-admin, the Auth fails and you are redirected to the login screen again. In addition, despite disabling email Authentication, this is repeatedly requested and no email is sent. I believe this is because of Fast Velocity Minifier, but even with this plugin disabled, and all caching utilities, the issue persists.

I think I can work around most of the odd behaviour, but the LinkedIn Auth concerns me – if it doesn’t work for me, it won’t be working for most of my users.

Thanks
