The issue is with the first add_action function call.
If a function named my_login_logo does not exist in your code, adding an action that would call it will result in the warning or an error.
Looking at the WordPress docs:
https://codex.wordpress.org/Customizing_the_Login_Form
You should use:
function my_login_logo() {
echo '<style type="text/css">'.
'h1 a { background-image:url('.get_bloginfo( 'template_directory' ).'/assets/my-logo.png) !important; }'.
'</style>';
}
add_action( 'login_enqueue_scripts', 'my_login_logo' )
There are a few other examples as well, which includes changing links, further styling, etc.
It shouldn’t, no, though ultimately the only way to tell if something is impacting performance is to use a monitor or conduct performance metric testing. If you’re not currently seeing higher levels of traffic, it will be a little harder to do that since with low levels of traffic (or no traffic), you can’t really tell unless it is something major.
