How to Fix Safari Automatically Unzip Files
If you're seeing this error message, and if you're using a Mac then it happens because zip files automatically get unzipped on Mac when you download them. Do the following so your zip files don't open automatically after you download them:
- Go into Safari Preferences.
- Page titled General.
- Scroll down to the bottom.
- Deselect the box with the text "Open safe files after downloading".
- The themes and plugins will now download as a .zip file that uploads seamlessly to WordPress.
