Hi Charles,
Thanks for reaching out!
I believe that is because you might have had some scheduled imports from Facebook in the past. We had to remove that option from the plugin due to the changes Facebook has made to their API, but the data is still in your database. And that is probably causing the issue.
We are aware of this and a fix is already on the way. If all goes well, then the fix goes out early next week.
Hang in there, the solution is coming.
I am going to set the status of this ticket to “pending fix” and we will update it once the fix is released.
If you have any new questions or issues please create a new ticket and we’ll help you out.
Thanks and cheers,
Andras
