Enjovia has a few things that you need to do before your store can start selling.
This information can be found in your dashboard under Settings > Store Settings > Go Live (tab).
If you see these all ticked, simply press the box next to 'Go Live' and this will turn your store on.
If you don't see all of these ticks, please take a look at the link below to go through the steps of creating your Enjovia store.
