In version 0.2 of this plugin the Login Logo only appears on the standard Login page: wp-login.php. The custom logos do not appear for any actions as stated by Rafael Poveda - RaveN in the post : http://wordpress.org/support/topic/plugin-custom-login-logo-lite-actionregister-actionlostpassword-logos-not-updated
To make this plugin work across all actions a change is required to the code. Edit the custom-login-logo-lite.php located in the wp-content/plugins/custom-login-logo-lite/ folder.
Change the following line of code:
add_action( 'login_form', 'custom_login_logo_lite' );
add_action( 'login_enqueue_scripts', 'custom_login_logo_lite' ); // Works on all login pages
