Error validating access token wordpress
It looks like Alex actually recently fixed a bug where authentication breaks when a channel is setup and the user changed the Facebook password. However, It looks like you're running 7.0.3, so it's possible we missed some corner case in testing this issue (related to a different domain).
Have you actually just tried de-authorizing the application in the user's Facebook I'm sorry. Log into the Facebook profile of the user that you have set up as the channel owner.
This may be because the user changed the password since the time the session was created or Facebook has changed the session for security reasons.
I am getting the following error Facebook API Error: Error validating access token: The session has been invalidated because the user has changed the password.
The access token secret type as described by Section 5.3.-Melissa This error means that the page ID that is being used is not valid, so something is probably incorrect in how the channel is set up or permission to the page., and I am using the URL of this blog (https://benbiddington.wordpress.com) to collect request tokens.Also, I finally updated the Facebook App configuration guide.
Added a feature to limit the posts displayed in the feed to only posts that were directly posted to the timeline associated with the Facebook ID you assign to the plugin.Part of the problem of changing domain names is that a lot of things like the Facebook Channel get invalidated.
