Clearing the browser cache doesn’t help. Nor the WordPress cache on the site. I also cleared the CNS cache on my computer. But I ran it through PageSpeed, and it’s also seeing the old fonts like I am.
I’m not sure which site I asked you to look at in the private info before, but please take a look at the one I’ve put in now. Are you seeing Georgia or a system font?
ETA: Eh, I just tested it on a test install with hardly any plugins or snippets. I’ll start testing it on my regular site to see what’s conflicting.
