The error code is from the "/" being used.

 

Have you tried using the whitelist instead?

 

The keywords you put look to be correct, when you tested youtube did you just use the smart phone app or a computer browser?

I've tried using both the smartphone app and accessing the router's dahsboard via a browser. Neither are consistently effective. A whitelist is not a viable option as it is a limitted set of sites that I need to block, rather than a limitted known set of sites that I want to allow access to. On the occasions when the parental controls do work, when you turn the parent controls off, the effect is immediate, allowing instant access to all websites. If you turn the parental controls on, it never works immediatly (other than to block access to the router's dashboard via a browser for the named devices) but it is at best inderteminate whather or when the blacklist will be opperational.
