Is there a plugin or tutorial to do the following?
1. Eliminate the theme appearance options a new user site can make. (I'd like them to use my exact default child theme and not be able to make any edits.)
2. Allow the new user to upload a banner/logo to the top of the content area or upload a logo with contact information in a sidebar widget.
BTW: I'm trying to make an etsy type site so want the stores to all look like mine with the option for a new user site to add their own logo and contact info.
