"Broken" or "Missing" Stylesheet (style.css) file when uploading the theme zip file. How do I fix this?
This error message does not mean that the theme you have purchased is broken, it just an indication that the something has been uploaded incorrectly. Luckily, there is a very easy fix.
Simply put, you need to unzip that main folder that you downloaded from ThemeForest and then upload the folder that's INSIDE the "Theme Zip" folder - usually named after the theme - ie: "campus.zip" or "polytechnic.zip".
Here are some quick steps:
01 - Download the "All files and documentation" option
02 - Extract all files
03 - Upload the theme zip folder found in Theme_Installable_ZIP or Theme Zip folder
