Custom CSS

That’s a good question. What theme are you using? Where is the custom css stored?

Let me know on those two items and I can test quickly.

Also, for future reference, best practice would be to use a child theme though, and then you could do whatever you want with the parent theme and your custom styles would always be safe. You can read about that here:

Thanks!

Glad to hear @vickiemitchell96 — how exactly was this resolved? Was the custom CSS kept untouched when you rolled back? Would love to hear about your experience for others to benefit from as well.
