(default will be English)

The problem with Gtranslate is that the free version does not allow you to override the automatic translation. So, if you just need to override even one word from the translated theme setting strings you need a paid subscription. This will cost a lot more than the theme itself. In my case this is not feasible and makes the vw-startup-pro theme unusable.
