I have "Discussion and Social Networking" set to block, but I've added the following as specific sites to allow...
facebook.com
0.channel25.facebook.com
...however when using Facebook, Safety Minder continually pops up a window saying http://0.channel25.facebook.com:80 is not allowed.
Is the :80 causing the problem? I can't use :80 in the "allow" entry field - complains that it must begin with http:, which is already there. So there is a parsing bug.
Yes, the house rules have been updated.
