I can edit the .css for my site only via the Theme Settings tab - if I make changes to the style.css by accessing the cPanel nothing happens. I prefer to edit in the cPanel because it's easier to navigate and also because I am able to see that the edits have been saved. (I can't find a file in the file manager that seems to contain the edits I make via Theme Settings.) I am using a Custom Community child theme. I've tested editing the .css for a plug-in installed in my child theme via the cPanel, and there was no problem doing that. AND the changes showed up immediately so it's not a cache issue. Nor is it a permissions issue - both .css files are at 777.
