This tutorial shows how to resolve the “Theme is missing the style.css stylesheet” error while installing a theme in WordPress.

Why does it happen?

• Usually, this error appears when you are installing the wrong theme zip file.
• The .zip archive file is incomplete or corrupted, due to incomplete download (This situation is pretty rare).
• Non-WordPress Theme: When the zip file uploaded is not a WordPress theme.

How can it be fixed?

Step 1: Unzip the archive downloaded from ThemeForest. For example, if you downloaded the Oklahoma theme, after unzipping the archive you will have the following folder structure:

Step 2: The correct file that needs to be uploaded in WordPress, in order for the theme to be properly installed, is the oklahoma.zip archive, inside the /theme/ folder.

Step 3: After installation, you can also install the oklahoma-child.zip archive (It is the child theme for Oklahoma theme).

Note: If you are using any other theme from ModelTheme, the folder structure will be the same.
