When installing a WordPress theme from your Dashboard (Themes > Add New), you may see the error "Stylesheet Not Found" if you're uploading a zip folder.
The good news is that it's really easy to fix!
1. On your computer, find the zip you downloaded using Windows Explorer, Finder, or your preferred file searching tool.
2. Double click or right click and extract the files.
3. This should open up the zipped folder and you should see another zip folder inside with your theme. (Good themes will also have documentation/a getting started guide here which you may also find helpful).
4. Don't unzip this one - simply upload instead!
