Popup does not appear

Is it still working on the newest MyBB 1.8.12? I set all the api keys and secrets correctly, added buttons to my registration template and after clicking any of the 3 buttons (Facebook, Google, Twitter) no "popup" opens. I'm just redirected to the page seen on the attachment. What am I doing wrong here?

Can you provide me a temp FTP account? I will check this out as soon as possible. Besides, Flyover works with the latest MyBB version as you can see from the live demo on MyBBoost.

I found out what is going on. I have set ACP > Forum settings > Forcing ppl to login... (name can be kinda different - I removed the English land, becase forum is Polish:P). That's why it didn't let me use your plugin and I have been redirecting to the login page. Totally forgot about such option.
But in the other hand this is a bug IMHO. I would like to block my forum content and force registering. But I can handle this pretty easy setting proper permissions for guests :)

I'm glad you have sorted it out on your own. This looks like something I can easily add given I have implemented the same thing in MyFacebook Connect 3.6.

But I'm still fighting. Can't log in using any of: Facebook, Google and Twitter...

Getting this error for Facebook:

Edit!
Getting the same message trying to log in here - using this forum's Facebook login. It is probably due to an Facebook API update :(

Unfortunately this is one of those errors I must debug personally. I would be glad to help you out if you PM me a temporary FTP account, so I can perform some debugging directly.

I have fixed the issue and it's likely I will push an update soon given it's high priority to have Facebook working again. The other providers should be unaffected.

You will *not* need to update the entire plugin as it's just an update to HybridAuth.
