[nabbi95]

i installed everything but magicmirror does not start
it shows create config file

[Cyber2141]

It must be a syntax error

[memoriasIT]

It lacks a comma, still I haven't managed to get it working

   modules: [
        {
			module: 'MMM-MP3Player',
			position: 'top_left'
        },
    ]
