[5.3] ErrorException: Invalid argument supplied for foreach()

Hi, I have an application uploaded to shared hosting and I can't call "artisan" command. And always the command returns:

> /usr/bin/php artisan 
[ErrorException]                         
  Invalid argument supplied for foreach()

Here are some logs:

stdClass Object

    [job] => Illuminate\Queue\CallQueuedHandler@call
    [data] => stdClass Object
        (
            [commandName] => Illuminate\Mail\Jobs\HandleQueuedMessage

        )

What can I do to know what is the problem?

Thanks
