blueamrich If you press F12, do you see any errors in the dev tools? I had the same thing happen when I updated from 19 to 23 and the dev tools (network tab) was telling me that the css requests were blocked due to mixed content. Turns out that in my config, my base URI was still set to HTTP, yet my site is fully on HTTPS. I changed the base URI to HTTPS and everything works great now.
