Reply To: upgrade to premium

Let’s begin at start:
The plugin easyreservations is free and you can install it in many different ways, more details here:

After you’ve installed and activated it you’ll see a new menu in the Administration sidebar.
If you go into it’s settings there is a navigation on the top. The fourth entry should be “premium”, click on it.
On the bottom left you can enter your premium account details and download the modules afterwards. Just click on install all and then on activate all.

Hope this helps
