Class CreateTableName Not found php artisan

when i typed in console - php artisan make:migration create_website_table --create=website

than file created, I didn't edit anything and ran command php artisan migrate

now i want to rollback it and it says

[Symfony\Component\Debug\Exception\FatalErrorException]
Class 'CreateWebsiteTable' not found

The code of my migration Website class

<?php

use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateWebsiteTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('website', function (Blueprint $table) {
            $table->increments('id');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('website');
    }
}

Maybe there is some namespaces?
