By default, events have the "draft" status, which implies that you have a limited usage of the back-office. 

You can only register or check-in more than 10 contacts, and some features aren't activated (SMS, badges imprints, PDF badges...).

To activate your event, click on the padlock button "Draft event, click here to activate!" then enter the activation code, given to you by our sales team after validation of your estimate.
