I made changes to my existing WP theme in MS Expression Web, saved everything then uploaded the revised theme back to my server. The revised theme is not showing in my list of available themes in my WP Dashboard Appearance options. As far as I can tell, all the required files are there and they all show as having been revised today.
For those responding: I am not a programmer. I'm a photographer. I don't speak 'code'. Please keep responses simple and in the English language, not programmer language. Thanks.
