EasyBlog - Facebook AutoPosting Not Functioning

Easyblog is integrated with Facebook.
Attempting to publish blog post; while posting yet nothing happens.

Then I tried to troubleshoot and noticed an error when disabling Facebook on the user-end.
The Facebook app isn't in development mode; so I am lost as to why it isn't allowing to publish.

All I can think of is that I need to have both;
publish & manage pages approved by Facebook Development Team?
