We have pre-defined a user for the frontend and the backend of the component. This demo user has invoices, orders and is able to add events in the backend. The demo is being reset every 2 hours to be sure evrybody can make use of the demo at any time. So when you're being logged out the demo probably has been reset :)
Login to the Backend
As the demo is being reset every 2 hours you may also use your own credentials to create a login on the website.
