no HTTP after onlinefamily installed

having just installed onlinefamily, setting up with 1 child user, restarting computer several times, updating rules etc, I cannot access any HTTP webpages. Skype is fine. https pages are fine (such as norton, facebook, gmail. gmail tells me to enable cookies,which are already enabled. avast antivirus program update is fine. Pages are listed in onlinefamily activity report as allowed pages. They just show up as blank with that annoying 'done' at the bottom of the page. this is the same in firefox and IE.

I have tried disabling OF blocking for that user and still no joy. It is happy. I am not.

What has gone wrong? Any ideas?
