I have added the Suspicious and Uncategorized categorie in Web Security > HTTP/S > URL Filtering.. After settings apply, I came back to remove it.. But I can no longer make any changes to the URL filtering, as Everything I click apply to save the change, there is a Red box flashing around the "Allow.... / Block ..." at the top of the page.
The error message is: One of the values you entered is syntatically or logically incorrect... I have tried pretty much everything, clicking block mode, clicking all categories, etc. This error dosen`t seem to go away...
