Timeout fail to update an user using updateUniques()

I got this FatalErrorException Maximum execution time of 30 seconds exceeded when I'm trying to update a field in my User model.

my UserController:

function aktifkan($id) {
  $user=User::find($id);
  $user->is_active=1;
  return ($user->updateUniques() ) ? 'success' : $user->errors();
}

If I change it to $user->save(), yes it'll pop The username has already been taken error

my composer.json

my User.php

<?php

use Zizaco\Confide\ConfideUser;

// class User extends Eloquent {
class User extends ConfideUser {

    public static $rules = array(
         'username' => 'unique:users,username',
         'email' => 'email'
     );

    protected $table = 'users';

    protected $hidden = ['password'];

    public function getAuthIdentifier()
    {
        return $this->getKey();
    }
    public function getAuthPassword()
    {
        return $this->password;
    }

    public function getRememberToken()
    {
        return $this->remember_token;
    }

    public function setRememberToken($value)
    {
        $this->remember_token = $value;
    }

    public function getRememberTokenName()
    {
        return 'remember_token';
    }

    public function getReminderEmail()
    {
        return $this->email;
    }

    function accountType() { return $this->belongsTo('AccountType'); }

    function team() { return $this->hasOne('Team'); }

}

That's it. I guess my code is similar to https://github.com/Zizaco/confide#update-an-user

Thanks in advance
