Thanks for the report. It looks like it's very similar to:

Could you post the lines above

There are no lines above

Next time it does this I will look and post again.

Thanks.

Since the Pi-hole 5.1.1, Web I/F 5.1 and FTL 5.1 upgrade, I am getting a spinner on Clinet activity over last 24 hours, Query Types, Queries answered by windows 100% of time.
Clearing caches, restarting DNS resolver, restarting RPi running pihole do not fix it.

This has almost always been cleared by a browser cache clear. Have you tried a different browser and/or different client? If so, is the display the same in all cases?

Thanks jfb. I reinstalled pihole just before reading your post but did the browser cache clear anyhow and it has now come good.
