1. Can you check to see if the new user is activated? Go into the User Manager section to find this.
Yes user is activated in Joomla user manager.
2. When the profile is created, is the user actually logged in our your site at that moment? If you go to index.php?option=com_users&view=profile can you see standard Joomla profile?
NO . when the user appears to have logged in when the profile tab is selected the message .... Error
Please log in or sign up to view or modify your profile. Although the message on the previuso page states "You have successfully signed in with your Yahoo credentials.
3. Can you check that the user is in the correct user groups? There's also a setting in JFBConnect backend > Configuration > General on which user group new users will be placed into.
New User Registration Groups = Registered
4. Can you provide a URL you're expecting to be able to access once you're logged in via Yahoo? I'd like to see it in action if the above don't help narrow down the issue.
