Testing use of Ultimate Facebook.
Multisite install..
Newly created App functioned tested ok and api entered.

However we get a "Please, enter correct Facebook API settings"
Under the settings.
What is entered is correct.
The permissions tab shows the data search endlessly running..

Testing on subsites: appears to post to FB and proceed as would be expected.

Cannot seem to trouble shoot.
Thought it may be a latency question- it has been over 12 hours since app created and given green light..
