Hey Calvin,
I'm a bit lost here. Can you tell me where exactly this error is occurring and what actions are triggering this error? Perhaps some screenshots would be nice to help understand your issue better.

sure in the backend when I go to the pending queue - I am able to approve the post or reject it. It is on approval in the editor area so you open the post to view it and then you have a button to approve it - on clicking that button I get this error. I am eventually able to approve - but I get the error and have to do the approval in the screen outside the editor - but I did see similar error there as well. It could be that my user is setting a password on the post ? I am not sure ...I will keep an eye on it when I get more to approve..

Hey Calvin,

I am sorry for the delay of this reply,

Error Validating Access Token: The Session Has Been Invalidated Because The User Has Changed The Password.

This error is Facebook generated and detected your Facebook account changed the password recently, perhaps you can try click `Revoke access` button from backend > easyblog > autopost > facebook then try re-authenticate again with your Facebook user account in Easyblog and see is it still hitting the same error ?

If yes, perhaps you can provide us with your Facebook account access so we can better have a check?
