Register page after FB click

First, please make sure the JFBConnect backend > Configuration > General > 'Enable Automatic Registration' setting is set to Yes. This will automatically create users when a user logs in with their social network credentials, without having to go through the mini-registration page that you're seeing. However, some social networks do not support the fetching of email addresses from the social profile data, which is a requirement for us to support the Automatic Registration for that network.

In order to get the captcha to show in the login/register view, first enable the appropriate Captcha plugin in the backend. Then in the Joomla Global Configuration area, make sure to set the 'Default Captcha' setting to that plugin.

If you've tried both of these steps and are still having problems, please let us know any more details on how you have the captcha set up and which social network that you're trying to log in with.
