未找到“Illuminate \ Encryption \ Encrypter”类

Question

I moved my Laravel application to production on a shared hosting. Now, I am getting this error message on all my pages. Not sure how to solve it. I believe I was using another version of Laravel when I copied over my vendor folders. I think I was using 4.2.6 and now I am using 4.2.8 on my dev.

Class 'Illuminate\Encryption\Encrypter' not found

`/vendor/laravel/framework/src/Illuminate/Encryption/EncryptionServiceProvider.php
     *
     * @return void
     */
    public function register()
    {
        $this->app->bindShared('encrypter', function($app)
        {
            $encrypter =  new Encrypter($app['config']['app.key']);

            if ($app['config']->has('app.cipher'))`
