Cannot load Facebook page - just shows as text. Have added as an allowed page in parental controls. Can access via 4G on my mobile, but but not over BT internet on any of my devices. Any ideas? Thanks!
Its most likely that BT Web Protect has been enabled by BT.
Login to MyBT and look at your broadband extras. You should see BT Web Protect.
If its enabled, then disable it
Also Facebook needs a number of sites added to Parental controls, as the images come from a different domain.
I finally found a workaround, by switching on VPN in McAfee. I now have access to Facebook. Still doesn't work without it, though, but at least I have found a solution that works for me.
