I don’t know.
I have it working now, but I’m not 100% sure why.
For one thing I realized I was calling “PT-Sans” instead of “PT-Serif” which is what I was loading from Google. That’s my fault.
However, even after fixing that I continued to have the problem until I cleared the system cache. And after I did that the first time, I had to then do it every time I made a change. Until suddenly I didn’t.
I sent an e-mail about the Quix and Unite updates. Would be nice to have them.
