Returning blank "Login error!"

I just installed this today (on a fresh wp isntall), and get this error too : (

I think I just figured out the issue, at least for me anyways. You need to go in to your WordPress Dashboard, then Settings/Nextend FB Connect, then under Settings you’ll see “Fixed redirect url for login:” type in your domain here and then make sure it matches the Site URL in your Facebook App under the “Website with Facebook Login” tab. Then click the ‘Save Changes’ button in your WP dashboard. Hopefully that helps!

Still getting error after following philosaphylas advice.

HOW TO FIX

Repair the options table then run DELETE FROM wp_options WHERE option_name like '_site_transient_%'

I tried both suggestions above.

And this….
Better WP Security plugin limitations
Disable “Filter Suspicious Query Strings” option
Disable “Reduce comment spam” option
Disable “Prevent long URL strings” option

I even disabled Better WP Security completely.

Any other ideas @nextendweb ?

Like usual, after hours of tinkering AND posting in a forum, I figure it out!! Minutes later too. haha

In your FB Developers App
Settings >> Security –

YES – Client OAuth Login
NO – App Secret Proof for Server API calls
NO – Embedded browser OAuth Login
NO – Require 2-factor reauthorization

I had “App Secret Proof for Server API calls” and “Embedded browser OAuth Login” set to yes. Setting them to no fixed it….for me.

Don’t for get to set Better WP to:
Disable “Filter Suspicious Query Strings” option
Disable “Reduce comment spam” option
Disable “Prevent long URL strings” option
