demo4.traccar.org - locked up

I put in an invalid location in account long and lat. Now when I login all I see is an error message saying invalid long and lat. Who can clear my location long and lat on demo4.traccar.org? Error: Invalid LngLat latitude value: must be between -90 and 90

You can use API to change it.

Thanks - trying to learn how to write an API. This may take a while :-)

Problem solved.
After a little research I was able to access the interface -
login then from the error page go to demo4.traccar.org/settings/server
