Cannot access admin page

Hi, I have been evaluating Events Manager with Astra theme. In order to test membership booking for events I created a fake user (non-admin role) in EM. I logged in as the new user from another window. After making a booking of an event, I went go to the previous window where I still have the dashboard opened. But when I tried to navigate to another page, I got a message saying I cannot access this page. I am logged out from the Dashboard as an admin user. Please help. BTW my test website is running locally with a virtual machine installed.
