PHP 8 compatiblity

I updated to PHP 8.1 and got these notices in my logs / query monitor.

Verouderd	strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated	

    wp-includes/functions.php:7022
    strpos()
    wp_is_stream()
    wp_normalize_path()
    plugin_basename()
    add_submenu_page()
    lyte_partners_init()
    do_action('admin_menu')


Verouderd	str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated	

    wp-includes/functions.php:2162
    str_replace()
    wp_normalize_path()
    plugin_basename()
    add_submenu_page()
    lyte_partners_init()
    do_action('admin_menu')

Are you open to fix this? Want me to open a PR somewhere?

Kinds regards,

Jaime Martinez
