When I try to install the theme I get the following error"Installing Theme from uploaded file: themeforest-6808797-newave-wordpress-responsive-one-page-parallax.zipUnpacking the package�Installing the theme�The package could not be installed. The theme is missing the style.css stylesheet.Theme install failed."I tried to install it twice. I Downloaded the .zip again from themeforest and tried again. This is on WordPress 4.0.1 Thanks

There are two files you can download from envato: main archive and the installable wordpress file.

The main archive contains the theme folder but also demo data and documentation. That file cannot be installed.

the file that should be installed is newave-theme.zip (can be found also in the main archive folder) or downloaded directly from envato.
