I am having trouble with the popup messages that should appear when hovering over the monthly calendar. When tooltips are set in 'configuration' to 'bootstrap' the tooltips appear in HTML code rather than the proper information. When I set tooltips to UIkit i get an error 'proplem with popups localhost' reported when I exit the configuration. With this setting also, when hovering over the calendar I only get a limited amount of info shown, just the event name, not what is shown in your online demo. Are the popups an extra that is not in the 'free' version?
