Displet "Top Blocked Domains" shows "No Data"

After having updated PiHole to the latest release this morning (Core v6.4.3, FTL v6.7, Web interface v6.8), the navigator "No Data" under the "Top Blocked Domains" displet as depicted with:

Debug token has been uploaded with:

Any insights into this appreciated so that I can look further into this problem.

Have you tried reloading with CTRL-F5 in the browser?
And cleared browser cache and cookies for the pi.hole webGUI?
Have you tried on another device or with another browser?

Yes, I have hit CTRL-F5 on the browser to refresh the web page content.

I am calling up the same web page on a different PC, the same results.

You have more than 300 regex entries on the excludeDomains option:

This is probably filtering all lines, resulting in no data left to be shown.

The filter to exclude domains is OK. Before the upgrade it did show all additional domains that have been blocked, but not been filtered out.

If I remove the filter, it shows the TopN domains that have been blocked.

It means the domains are received by Pi-hole, but your option is filtering them, as intended.

You need to check your regex rules to make sure they are not excluding more than you expect.

Yes, this is correct for now. I am observing this behaviour now with regards to the filtering options applied.
