Settings message when no active events

I get this message on my website (event page) when there are no facebook events planned since I updated to version 1.9.6: “Please go to the Facebook Options page of our plugin and look for the “Change Post Limit” option and add the number 7 or more. If you are trying to add a Personal Facebook feed and you are seeing this message too, please note: Personal Facebook Accounts generally do not work with our plugin.”

I have changed the post limit to 7 but the message keeps showing up…

What should I do to get rid of this message?
