问题
I'm posting automatically news from web site to FaceBook: www.rybnik.com.pl -> rybnikcompl
It worked fine for a few months.
But 2 days ago I noticed error:
"The user must be an administrator of the page in order to impersonate it."
As I know nothing changed in user, application rights, access token, etc.
The sending script (in PHP) is also fine - it is still sends post from another sites to FaceBook (of course with another ids and tokens).
The strange thing I saw is that on the page: https://developers.facebook.com/tools/explorer/ name of my application disappeared from list "Get Token" (but still exist on list "Application: Graph API Explorer" on the same page).
So I (probably) can't generate proper User Access Token.
Application permissions: user_photos, user_videos, user_friends, email, manage_pages, publish_pages, publish_actions, public_profile
Have you some suggestion what is wrong? How to fix it?
