Facebook API Error: Error validating access token

1. Your image shows "You haven't logged into any apps with Facebook". Have you actually logged into your new Joomla site with your Facebook credentials yet? If you have not logged in via FB credentials, not Joomla credentials and not on facebook.com, then you won't receive prompts for scope/permissions.

2. Is you Facebook application live? If not, is the FB user that you're attempting to log in with an administrator of the app?

OK I did that and now the Facebook channel is complaining that the app has been deleted. Is there something else I have to reset? Should I uninstall JFBConnect and start over?

Make sure to change the App ID and secret in the JFBConnect backend > Configuration > Facebook section. If the error occurs in the channel, it'd be fine to just delete the channel and create a new one. Also, if you have any users mapped in the JFBConnect User Map area, you should delete those mappings, as they're tied to the old application.

-Melissa

The only reasons you should get that are:
* The account you have set in the channel has an incorrect Joomla user associated with it (one that isn't associated with a FB account)
* The Facebook Page you selected is incorrect or not owned by that user
Both of those things shouldn't happen if you deleted the user mappings and FB Channel. I hate to say 'try again', but can you delete the usermappings, possibly even create a new user account on your site, and try setting up the channel again with that?

I hope that helps,

Oh by the way, do you have a description somewhere of what you did to create your login/register dropdown and subsequent popup?

Our Common Support Questions for SCLogin addresses this with the "How can i open the SCLogin Modal Popup with a regular link?" question.

Can you take an image of the new Facebook Developer Area you're seeing? We just went through the documentation step by step and it was spot on for what we see. Facebook is known for rolling out new developer area updates and it's possible one is going on now, but we haven't heard of it yet.. which is a bit surprising.

As for the error message, can you double check that you created a "Web" application in Facebook. That shows up as a "Website" section in the Settings -> Basic area.

Also, in the Settings -> Advanced section, verify the following in the Security section:
* Server IP Whitelist is blank
* Update Settings IP Whitelist is blank
* Update Notification Email is blank (though this shouldn't matter)
* Client Token is "None"
* Require App Secret - No
* Allow API Access to App Settings - Yes
* Require 2-Factor Authenitcation - No

Thanks,
Alex
