Thank you Anchises.
But the plugins are too laggy, so i found another way to change it.
This is how it works:
Go to your “functions.php” , and put this in it
function custom_login_logo() {
?>
<style type="text/css">
body.login div#login h1 a {
background-image: url('YOUR LOGO URL');
background-size: 289px 289px;
height: 289px;
width: auto;
}
</style>
<?php
} add_action( 'login_enqueue_scripts', 'custom_login_logo' );
