Installation fails with error: No valid plugins were found

Problem: RightPress plugin installation fails with error message “The package could not be installed. No valid plugins were found.”

Cause: Envato packs the plugin file into an outer zip file which also includes license text files and related material.

Solution: Either pick the “Installable WordPress file only” option when downloading a plugin from CodeCanyon or unzip it on your computer first and upload the actual plugin file that will be inside.
