I just tried to remove all references to Google Fonts from my blog (which is using WordPress) because they can be a issue under the GDPR. There are many descriptions on how to do that and various plugins that claim to do it for you. I tried several ways, but none seemed to work. There was always one GET request going to Google.
Then I realized that I was still looking at my blog logged in as admin, which calls several WordPress tools, one of them apparently is using Google Fonts. So, I used a different web browser which is not logged in on my site. And guess what? No requests going to Google at all.
So I had – again – wasted more than an hour for a bloody GDPR issue.
