Hi Pas,
This is a known issue and it has been fixed internally. Can you download the attached file and apply it into the following directory?
JoomlaFolder/administrator/components/com_easyblog/includes/oauth/adapters/facebook/client.php
After that, revoke access and resign in Facebook in the autoposting section.
Let us know how it goes, thanks.

Hi Raymond.. thanks for the quick response... unfortunately if changed nothing...

Hey Pas,
Can you provide us your Facebook access at the Optional Information area so I can investigate this? Thanks.

What do you mean Optional Information Area?

Attached is everything in this page

Hey Pas,
I mean your Facebook username and password that is used to login into Facebook. Because I would like to test revoke and resign your Facebook account in the app.
You can include the information here: http://take.ms/zURK7

I got it work.. I just re-REVOKE Facebook Account.

Thanks for your help.

Understood Pas and thanks for informing us.
You are most welcome. Glad to hear that your issue has been resolved now.
