This settings.json now works for me:

Code:

{
    "port": 5000,
    "log-level": 4,
    "pid-file": "/var/run/pilight.pid",
    "config-file": "/etc/pilight/config.json",
    "hardware-file": "/etc/pilight/hardware.json",
    "log-file": "/var/log/pilight.log",
    "send-repeats": 10,
    "receive-repeats": 1,
    "hardware-file": "/etc/pilight/hardware.json",
    "webserver-enable": 1,
    "webserver-root": "/usr/local/share/pilight",
    "webserver-port": 5001,
    "webserver-cache": 0,
    "whitelist": "",
    "update-check": 1
}

Changes compared to your settings.json:

Code:

    "port": 5000,
    "webserver-cache": 0,

While the port should not matter, I got the same error as you after I removed it from my settings.json. Changing webserver-cache from 1 to 0 solved the issue for me.

p.s. if you still have issues with loading the webinterface in FireFox, clear Offline web content and user data.
