[sendxt]

The problem is after move processwire from one server to other, all work good , but i can't coonecting to my admin profile, 'login failed'. 

I try change my home page :

$user = $users->get("user's name"); 
$user->pass = "user's new password";
$user->save();

but it still does not work

I don't know that me to do, maybe need put script to create new admin user? if you have such a script, give me please)
