Welcome to McAfee Communities. Although I do not utilize (Family Protection) as I have included with my "McAfee Total Protection" Suite ( Parental Controls).
Which seems similar in Protection/Settings. It seems that in your (Optional Settings) you have either Allowed/Disallowed a particular URL/Site?
Or either in your (Custom Settings) have disallowed certain critera as (Social Sites/File Sharing/etc...You may try going back to the (Custom Feature Settings) and distinguish which area of the individual settings that may have to be allowed?
As I am not familiar with the particular settings with-in (Family Protection) I can only suggest that you enter your Password/Hint and check the above mentioned. As (Family Protection) seems to be a "Stand Alone" feature, I cannot suggest you to go to the (Help) area for a Step-by-Step Guide and Tutorial on how to access and use your McAfee Features.
So therefore, unless someone picks up this thread, whom is more knowledgeable in regards to (Family Protection) as a whole. I recommend contacting Technical Support, and explaining your issues for assistance. It is (Free) and can be reached through the following Link Provided; McAfee Consumer Products - Types of Support
I apologise for being in-capable for supplying you a definitive answer to your issue, however I sincerely hope that the LIink provided will hope fully resolve your issues.
Edit; I might add for your benefit, and better assistance. This thread be moved to (Family Protection)
Wishing you all the Very Best,
