I discovered a mild font problem after updating to GP Premium 1.10.0.
My font selections weren’t working anymore. First I checked in the Customizer, and it showed “inherit” everywhere I looked. I finally thought of checking in the GeneratePress panel, and sure enough, “Typograghy” was no longer enabled. After re-enabling that, I was able to get my fonts working again.
I apparently didn’t notice it immediately after updating to 1.10.0, probably due to my browser cache not showing the lack of fonts.
If this were a courtroom, I suppose one of the lawyers would have objected with “asked and answered”. 🙂 I did try to search for this problem before posting, and didn’t see a match. I hope this helps, and maybe I should mark it as solved?
I just remembered one other possibly pertinent fact. Before I did my update on the above, I got the usual WordPress message in admin that there was an update for GP Premium available. I usually just delete the old version and install the new version, which I think I learned to do here at some point.
Still, I thought I would try the auto-update anyway, and I got some sort of failure error, which unfortunately, I didn’t save. Maybe this blew out a setting or two.
