There is a problem with boolean values. You need to add them as string attributes manually. That's a known issue in the last release.

java.lang.Boolean cannot be cast to java.lang.String - ClassCastException (ExtendedModel:89 < PropertiesProvider:39 < NotificationMail:57 < ...)

Can someone please explain how to fix that

Yes please!

"You need to add them as string attributes manually."

...for Traccar Demo Servers???
(Error: ClassCastException)

Those attributes should be string type instead of boolean. Unfortunately there is no way to do it through official web app. The only way to do it is via web API:
