I can't add it to the official themes list (https://wondercms.com/themes) if it cannot be install through the WonderCMS engine (Settings -> Themes & plugins).
I already prepared the right zip file for you, which can be used for installing through the engine AND through FTP.
Here is the file: download/file.php?id=91
Just upload this one as a release (like the other one), and we can add it to the official themes.
