unsupported_grant_type

Hi @chetan0412

If you’re looking at the Debug Information from the Debug menu:

View post on imgur.com

then that page is only for checking whether your site can communicate with the provider’s. So the only thing that matters is the success or failure message:

View post on imgur.com

If the connection is successful, you should ignore everything else you on this page.

What’s the exact login problem you have? Do you get any kind of error message when you attempt the login?

The most common error is the “User registration is currently not allowed” message. It happens because Nextend Social Login inherits the WordPress – Membership settings ( WordPress admin menu side bar > Settings > General > Membership – Anyone can register ) This means if you have that setting disabled, the registration won’t be enabled with Nextend Social Login either.

If you only want to enable the registration with Nextend Social Login, regardless of your WordPress settings, then you should navigate to:
Nextend Social Login > Global Settings > General tab > Membership
and change it to “Enabled”:

But if you see any other error when you try to log in, please copy it or send me a screenshot where I can see it.
