can't install the theme. wordpress is saying that "Stylesheet style.css" is missing
The "missing stylesheet" error happens when one tries to upload the entire theme package, downloaded from ThemeForest, which includes the theme, plugins and a child theme.
Please unzip that file. Inside you'll find recycle.zip. This is the theme file which can be uploaded to WordPress.
All the best,Timea
