This error means that you are logged into wrong personal profile, associated with your PromoRepublic account. What does it mean?
When connecting a business page, your PromoRepublic account must be synchronized with a personal profile, that has an assigned Editor or Admin role on this page.
When the page is added, its Admin profile is automatically attached to your PromoRepublic account as the host. Thus, your PromoRepublic account has a specific Facebook profile associated.
In order to ensure flawless posting such a personal profile must be authorized in the same browser at www.facebook.com to set the bond.
In case you don't know which Facebook profile is the host on your PromoRepublic account, check other Facebook pages in the Calendar on the left and try to remember what profile is the admin there.
Or you can check it on the business page itself. Go to the page settings, find Page Roles section and you'll find what you need there (pictured below).
In case this doesn't help, please email us at [email protected].
