As of today April 9 2016 the Warcraft wordPress theme is configured for mobile responsive browsing.
The theme is now mobile and responsive*. Theme has been integrated with Slicknav Menu plugin and let me highlight this – the menu integration is multi-level Jquery touch responsive menu (which is very good). You can resize browser window on demo site, to see how it works.
(*featured image slider and sidebar disappear, bottom 3 widgets stack vertically and are visible)
So If you have purchased the theme before this date and you want to have responsive site you need to download and reinstall the theme and Slicknav menu plugin.
Theme update is really easy, simply delete the one on your site from WP admin interface and upload and install the updated theme zip file and activate it. (Keep in mind that if you have made some customizations to the theme files they will be lost, unless you back them up. But If you have made customizations you probably know this) Always recommended to use child-theme for your own tweaks.
There has been changes with menu. (changes were made in header.php, styles and functions.php file)
➡ For mobile menu to work install SlickNav plugin (look in your downloads) and configure as shown below.
➡ Only the CSS Menu ID #primary-menu entry is mandatory, rest of the colour configurations are recommendations to fit the theme.
So go to your WordPress Admin panel.
➡ Go Settings > Slicknav Menu
See image below on how to configure the plugin
