There was an issue with parental controls a few days ago, sorry for the problems you were having.
It should be sorted now, can you access that site again?
I have the same problem - cannot connect to https://www.thewinesociety.com, unbelievable! I did not activate or request Parental Controls, when I try to override it says I'm not the account holder (though i can connect to myBT). I activated and deleted, no luck yet..
