My fully working installed theme (Sydney) is not appearing in the wp-content/themes folder. I have noticed this with other themes (some in the Twenty series) I've been "trying on" but I wonder why. To edit a php file I use Search in the Cpanel directory and it finds it where it should be, and clicking on that file in the results window takes me to the hidden directory and allows me to edit and save as expected. I even uninstalled the theme then reinstalled it with no effect. . So it's there, and healthy, but hidden in normal view. but why?
