How can I install the theme?
First of all you need to unzip the files that you downloaded from ThemeForest. The unzipped file containers many things like documentation, psd files, licence etc. so you just need to upload the novus.zip
If this method does not work for you, connect to your ftp and go to wp-content/themes then upload the unzipped novus.zip file which is under the main downloaded folder.
Once you have uploaded the files succesfully, you need to activate the theme on your Wordpress Admin Panel. Appearance—> Themes
