I have been styling the site over the past few days with no problem and now I suddenly can’t change change anything in the theme options. I have been using a mixture of changing methods previously in both the theme options and the custom.css file.
Earlier I re uploaded wordpress with a fresh install and the same for the Enfold theme.
No worries a worked this out. It was not a problem with the theme whatsoever. It is the plugin W3cache. As it caches pages it means you are viewing a cached page therefore css updates don’t happen immediately.
