I've installed the wordpress social login (as advised

I've installed the wordpress social login (as advised by you in a previous post), and because it contains the linkedin social profile, which I definitely want to have in my social connectors.
Using yours ultimate facebook plugin, logging in to WP works (so I consider my FB app to be configured correctly).
But for the WP social login I get some error warnings.
Any idea what can be wrong?
On my staging environment I had the twitter login working, but I moved my site to production, and twitter connector/login is no more working either.

Can you please help out?
