Error 500 after renaming my Laravel Project beginning with a number (how to resolve)

Had a Laravel App running on a remote server.

I wanted to change the App name, so from the home directory of my application I entered the command "php artisan app:name 1BV"

I thought this process was foolproof since artisan will take care of changing all the necessary config files.

However it's not the case, and when I try to view my website I get Error 500. If I try to run any command with "php artisan" like to re install or reverse to the original name "app", I get the following error in the command line:

root@Debian-87-jessie-64-minimal:/home/noman/iotx# php artisan app:name app PHP Parse error: syntax error, unexpected 'BV' (T_STRING), expecting ',' or ')' in /home/noman/iotx/bootstrap/app.php on line 31 

FILE: /bootstrap/app.php around line 31 */

$app->singleton( Illuminate\Contracts\Http\Kernel::class, 1BV\Http\Kernel::class ); $app->singleton( Illuminate\Contracts\Console\Kernel::class, 1BV\Console\Kernel::class ); $app->singleton( Illuminate\Contracts\Debug\ExceptionHandler::class, 1BV\Exceptions\Handler::class ); 

My question is: how do I fix this project which has been named beginning with a number, or am I forced to reset and restart completely?
