Thanks for your patience.
I have attached my Whitelist. You will see ten web sites on that page.
Looking in /etc/pihole, I have list.1.blocklist.site.domains through list.25.blocklist.site.domains. This image shows part of that directory.
The listing goes on to list.25.blocklist.site.domains.
Those blocklists used to be shown on the Blacklists page before the crash. Now the blacklist page is empty.
It is that blank Blacklist that bothers me. Shouldn't it appear the same and show the Blocklists (1 - 25) as it did before the crash?
Will those Blocklists in /etc/pihole from (https://blocklist.site/app/) be updated when the system updates the blocklists? This is the Blocklist page from within the Settings/Blocklists tab on my Pi-Hole.
Again, THANKS for your patience and guidance. CraigM
