Submenu doesn't open in the mobile version

Hello kanstan,

Please try to disable all the active plugins, leave just Visual Composer to active, clear all your caches and install only the plugins that come bundled with our theme and rule out the conflicting plugins. It is important to do this because your untested plugins which you are using in the theme could interfere with the theme and might cause a lot of unknown issues.

Hope this helps and let us know how it goes!

Thanks for your understanding!
