Following are two OUT DATED threads for dump1090-mutability and for dump1090-fa.
These have become outdated due to changes made during upgrades in files:
“/usr/share/dump1090-mutability/html/script.js”
and
“/usr/share/dump1090-fa/html/script.js”.
If someone is aware of how to do it in latest versions of dump1090-mutability and dump1090-fa, it will help many if shared.
