Button Icons show up as text

Plugins & Plugin Development Reactor
1

I know this is a bit off topic, but I just noticed this when checking one of reactors. Many of the icons show up as text. For instance, when looking at the status of a reactor, what should be a green check mark says says ‘Check’ and what would be a red x says ‘Clear’. Many other button icons are doing this too.

Only one of my PCs are doing this and it occurs with Chrome, Firefox, and Edge.

I just don’t know where to start looking to solve this. Any hints or help is greatly appreciated.

Well after searching the net and not understanding most of the search results, I got a clue about fonts that web developers use that are downloaded. That sent me to my pi-hole server and I searched for blocked domains, one of which was fonts.gstatic.com. Further search on the pi-hole forum indicated it should not be blacklisted and can cause the effects I was seeing. Problem solved.
