Hi there,
migrating from 5.0 to 5.1 got all the queries flushed (and the percent blocked) on the dashboard.
"Client activity graph", "client answered by" and "queries type" doesn't load too.
Though, pi-hole seems to be functionnal (still blocking queries - 17 clients)
here is my token :

im not sure about doing a pihole -r at the moment
