I think following will provide the required clarification:
(1) The configuration changes were made only when I reverted to older and tried version of Armbian (Armbian_5.20_Orangepipc_Debian_jessie_3.4.112_desktop).
(2) The reason I made changes to configuration file /etc/lighttpd/lighttpd.conf is that the Piaware Radio Status page was not shown on “192.168.0.23” or “192.168.0.23:80”. Instead lighttpd’s Placeholder page was shown. I was trying to bring the Piaware Radio Status page.
(3) The configuration changes did not affect the pages “192.168.0.23:8080” and “192.168.0.23/dump1090-fa” These worked OK and displayed Skyview page with aeroplanes, both before and after configuration changes.
(4) When I changed the configuration, the Piaware Radio Status page still did not show on “192.168.0.23” or “192.168.0.23:80”. I have therefore removed the configuration changes I made manually in file /etc/lighttpd/lighttpd.conf.
In the older version (Armbian_5.20_Orangepipc_Debian_jessie_3.4.112_desktop), the Skyview map is working OK.
