sites blocked despite "Web Content Filtering" = "Nothing blocked"

[coyote3]

I disabled site blocking in Settings, but I'm still getting adult sites blocked. New OpenDNS user, running the Updater on both computers. How do I get free of site blocking, please?

FYI
I entered OpenDNS servers on both my computers (because I need them to both have a static IP for port forwarding). At this point I already had this site-blocking issue, but then I also entered OpenDNS servers onto my router for my wifi devices (I read on the Internet that this was OK since the computers would ignore the router's DNS).

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.

[coyote3]

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?

[rotblitz]

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
