"The package could not be installed" No valid plugins were found.
I used the built-in WP uploader. I tried twice. Once with a download of vantage.1.2.zip on my Desktop (Windows 8.1). Got the error message above.
Tried again with a fresh download in a different directory, same error. Using Google Chrome Version 36.0.1985.125 m.
Is there a trick I'm missing? Should I upload with FTP then try?
