OK, that fixed the CSS displaying issue!
I didn’t reinstall the child theme because it was the same one from before (not surprising) and that’s where the few changes I did make were so I didn’t want to lose them. The updated theme seems to have picked them up as it should.
Didn’t seem like there were many changes in the log that affect me, but I will check them out over time.
Thanks for the help. 🙂
