I apologize you were unable to connect your Facebook page to our Social Post feature as easily as you should have! I have taken a look at the Social section of your account and can see there is an error message appearing on this section of your account. Does clicking the “Reconnect Now” button allow you to successfully connect after all? If you are still interested in using this feature clicking this button is a great troubleshooting step to take. However if you would like to disconnect your Facebook account it can be done under the Integrations tab of your Constant Contact account.
I hope this helps!
