I installed Better WP Security and now my posts will not post the associated FB page.
Past posts have this error message: Facebook error: An active access token must be used to query information about the current user.
I also posted an item today and it did not auto-post to Facebook.
I did go in an uncheck the Filter suspicious Query strings under Tweaks but not sure if this is the right problem. I have also unchecked the Filter Request Methods.
I have also deactivated and reactivated the plugin, not sure if that did any good as I am still seeing the same error message on past posts.
