Facebook to post is not working

Dear Szabi, my Facebook to post is not working anymore. I renewed the credentials but it says always "Warning, the sesion cookies you entered in plugin settings are incorrect or expired, the plugin could not log in to Facebook! https://m.facebook.com/profile/timeline/stream/?profile_id=*snip*&replace_id=u_0_16 Failed to import results from Facebook. Then I tested the above URL. Facebook says "Sorry, something went wrong. We're working on getting this fixed as soon as we can." Please see also attached screenshot. May there is any fix needed? Thanks for your support.
