I am having a problem with the Customizer. The person I am doing the site for wanted cinzel from google fonts for the site title which doesn’t work when I’m in the customizer preview – it appears in lowercase even though the font is supposed to be uppercase:
Have you tried setting the Text Transform option to uppercase?
If you’re seeing the changes happen in the editor and Customizer but not the frontend, it likely means you have some sort of caching plugin/server caching preventing the site from showing the latest changes. Try disabling all caching while in development to avoid this.
I think I have it fixed. I disabled Autoptimize and then today I enabled it again. I was going down through the css settings and I saw “Also aggregate inline CSS?” was ticked so I unticked it and cleared the cache and it seems to have done the job.
