I got the same 590 & 774 error codes.
Just swapped out this plugin for “Facebook Page Publish 2” and everything authenticated fine.
Now let’s see if it posts anything to my Wall…

Thanks! I actually just switched to another plugin called Add link ti facebook, and everything worked well.
??

This is all brand new and it is happening on all my sites that use this plugin. It used to all work fine so I am assuming Facebook made a change and we can expect a plugin update?
