No Activity for the last...days

For the first few days, Online Family worked normally. Then I noticed after some days (I don't feel my son needs daily supervision) it showed 'No activity on the last seven days.' I contacted the Norton representative. He / she reinstalled in on my son's computer. I noticed that again. 'No activity...' was showing.
Today, a representative took an hour, spending most of the time on my (the parent's) computer. Then he / she said 'It should work now. I logged off and on again, and again it shows 'No activity for today.' I had put the address of a couple of porn sites in the 'Specific web sites to block' in 'Settings.' Then I found I could easily access them from my son's computer.

I'm not getting much help from the representatives so I thought I'd post here and see if you good people could give me any suggestions.

 

Thanks in advance.

It seems to be working OK now. Please disregard the above. Thanks to anyone for taking the time to look.
