Background

That plugin will not do it for you. You’ll either need to use a different plugin or create a child theme and then add this to your child theme’s functions.php file:

// Load login page style sheet
function custom_login_css() {
echo '<link rel="stylesheet" type="text/css" href="'.get_stylesheet_directory_uri().'/login-styles.css" />';
}
add_action('login_head', 'custom_login_css');

You will then need to create a login-styles.css file in your child theme to style the background.

okay, I’ve created a child theme and did exactly what you told me, but this didn’t change anything :/

I “have” to use this plugin because I use another plugin (Password Protected) which only works with Login Logo…

Any other idea?

But anyway – thanks for your help!
