Could not login by Twitter, Meetup, Instagram, GitHub

You have a fatal error on your page right now.

Notice: Undefined variable: ch in D:\xampp\htdocs\springk\administrator\components\com_autotweet\helpers\channels\xing.php on line 121
Fatal error: Call to a member function setToken() on null in D:\xampp\htdocs\springk\administrator\components\com_autotweet\helpers\channels\xing.php on line 121

Please let me know when it is resolved so we can look into Google further.

I just attempted to register with Google and it looks to work how I'd expect. I was brought to the registration page and my name, email and username were pre-filled. There was also the following notices at the top of:

Notice
Could not instantiate mail function.

Message
Google profile successfully connected.

So, it seems to be working for me. It's possible Melissa's account is blocked by Google (it happens sometimes since we login to many, many sites) or some other configuration problem with her account.

Above, it sounds like Google is working for you as well. Can you try testing with more accounts or finding out if your users are having issues? That will really help narrow things down. From what I can see though, everything must be configured right on your end or else authentication wouldn't work for anyone.

Thanks,
Alex

VK doesn't support automatic registration (fetching of the email address) so going to the mini registration page is normal too.
