If you have Windows Live Family Safety installed and enabled on your Windows 7 computer, and if when it must, Internet Explorer does not display the Windows Live Family Safety block page when a Web site is blocked by Family Safety, then you may have to ensure that Active Scripting is enabled.

To do so, Open Internet Explorer > Internet Options > Security tab > Custom Level.
Browse to Scripting section and ensure that Activescripting is checked.
Click Apply > OK.
It should help!
