No data in realtime user map

On my realine map i got the message “Es stehen keine Daten für diesen Bericht zur Verfügung” --> "there are no data…"
I have checked FAQ page The Real Time Visitors World Map is not showing data. - Analytics Platform - Piwik
No java errors and i have add the .htaccess file in the piwik root directory.
The user map on the dashboard is working. so Geoip also is working.
Is there any idea what is going wrong there?

Best regards
Othmar
