Why can’t I post to my Facebook Page?
Trouble posting to your Facebook Page often stems from Page permissions.
When your dashboard displays the message, “The user that last authorized this Facebook Page in Hootsuite does not have post permissions for this page,” the Facebook Page admin must change your Page role to admin or editor. These settings can only be modified by the Facebook Page admin from Facebook.com.
Why can’t I post to my LinkedIn Page?
Those wanting to post to a LinkedIn Page need LinkedIn Administrator rights to do so. The page creator or an existing Page Administrator can assign this permission from LinkedIn.
