After following the steps for the 4.1.26 upgrade on Laravel, when I try to re-migrate and re-seed the database, I am presented with `Laravel Unknown formatter "prefix"` error.

I add the nullable string to the User's migration file and the three functions to the User's model.

```
$table->string('remember_token', 100)->nullable();

```

and

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

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

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

```

Looking at PHP Artisan, it rolls back the migrations, migrates them all, it's when it moves onto the seeding of the database.

I know it's the update as when I go back to a previous version, it's all working correct.
