How To Fix “style.css missing” Error while uploading themes?

A common issue that can occur with users new to installing WordPress themes is a “Broken theme and/or stylesheets missing” error message being displayed when trying to upload or activate the theme.

To solve this simply unzip the theme package you downloaded from GPL Factory and upload the themename.zip file which is included (with the file being the name of the theme).
