I have a problem when I run the pibooth, the message is

I don't have buttons. It's possible delete or something for run the app?

Thanks,

Hi @ferranponce , can you provide your config file please? Seems that there is something wrong in it.

Can you also provide more info on your setup (OS version, camera used, ...)
