    It seems you forgot to clear your two local caches once after the settings change.  Caches can be really persistent.

    Also, ensure that your IP address is registered at https://dashboard.opendns.com/settings/

    Thank you very much for your helpful reply, rotblitz!

    You're right I didn't know I needed to attend to my Chrome browswer caches; so I did for the whole account (not just that machine which I could have done by logging out of my google account) on both machines.

    Though that still hasn't fixed the issue.

    I not only followed that article's advice to "Clear Browsing Data", I then also followed advice at https://www.maketecheasier.com/clear-chrome-dns-cache/ to
    chrome://net-internals/#dns
    chrome://net-internals/#sockets

    Before and after I did
    ipconfig /flushdns on both machines.

    I did these all a bunch of times in different orders. Then I rebooted.

    I'm not totally sure what "registered" means but I had added my IP on that Settings page:

    "I'm not totally sure what "registered" means"

    This is what I mean (from https://dashboard.opendns.com/settings/):

    Copy & paste the complete plain text output of the following diagnostic commands to here.  Replace example.com by the domain name of the site which should not be blocked but is.

    nslookup -type=txt debug.opendns.com.
    nslookup whoami.akamai.net.
    nslookup example.com.

    Thanks rotblitz, before I clicked to the screen I printscreened it looked exactly like the one you did.  Here's my text output from those commands with a sample adult site:

    Lol - nothing blocked! If you configure the normal resolver addresses instead of the FamilyShield ones, nothing will be blocked anymore.

    Thank you very much for diagnosing my issue, rotblitz!

    I had just gone with the fastest DNS server using DNSBenchmark (and it does make sense that would be a presumably relatively little-used FamilyShield one!).

    Do I correctly understand from https://support.opendns.com/hc/en-us/community/posts/360054654872-sites-blocked-despite-Web-Content-Filtering-Nothing-blocked-?page=1
    that to avoid FamilyShield I only need to avoid 208.67.222.123 and 208.67.220.123 , please?

    Yes, these .123 addresses are the FamilyShield addresses which generally block adult content. 
    The normal addresses are:  208.67.222.222   208.67.220.220   208.67.222.220   208.67.220.222
