Did you change the table variable in User/Member model?

class User extends Model implements AuthenticatableContract, CanResetPasswordContract {

use Authenticatable, CanResetPassword;

/**
 * The database table used by the model.
 *
 * @var string
 */
protected $table = 'members';

and error - SQLSTATE[42S02]: Base table or view not found: 1146 Table 'vdvizhenii.users' doesn't exist (SQL: select count(*) as aggregate from users where email = ******)

<?php namespace App\Services; use App\User; use Validator; use Illuminate\Contracts\Auth\Registrar as RegistrarContract; class Registrar implements RegistrarContract { /** * Get a validator for an incoming registration request. * * @param array $data * @return \Illuminate\Contracts\Validation\Validator */ public function validator(array $data) { return Validator::make($data, [ 'name' => 'required|max:255', 'email' => 'required|email|max:255|unique:members', // unique:users -> unique:members 'password' => 'required|confirmed|min:6', 'captcha' => 'required|captcha', 'birthday' => 'required', 'terms_agree' => 'required' ]); } answer in comment

It looks like user table is defined in 3 different place out of the box Laravel 5.

• 1. /config/auth.php ('table' => 'users',)
• 2. In User.php (protected $table)
• 3. In AuthController.php (there is a unique field validator as in @Kollley reply )
