I have just updated my pi to pi hole 5 and something has failed as i cannot see any info so for example if i go to the blocking page and insert a test site it blocks it but does not show me the ability to remove it.
I've modded the pi hole and added a few pages of my own to control lights 
debug token is: https://tricorder.pi-hole.net/ph1yct7clg
Did it work before you changed your local AdminLTE code?
Have you cleared the browser cache and reloaded the web admin page?
yes its worked for a long time and only stopped with new 5.12 update.
I also have this new error appear on pi.hole/admin/dns_records.php page "DataTables warning: table id=customDNSTable - Invalid JSON response. For more information about this error, please see http://datatables.net/tn/1"
Please post a screen snap of what you see on your admin GUI screen. In this forum, you can paste the image directly from your clipboard or local file into your reply.
Let's rule out your local code changes. Please backup your local changes, then run pihole -r and select "repair" to put back the local code.
Ok I've just done a repair that went through with a hitch but still same error and still no way to view block list
Please generate a new debug log and post the token.
Clear your browser's cache.
