“Deprecated” alert with PHP 8.x

Hi,

I use

WordPress 6.5.4

PHP 8.2.20

In my Blank WordPress Website with only your plugin I got:

Deprecated: strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /usr/local/lsws/domain/html/wp-includes/functions.php on line 7288

Deprecated: str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in /usr/local/lsws/domain/html/wp-includes/functions.php on line 2187

Deprecated: Creation of dynamic property AdminManagementXtended::$textdomain_loaded is deprecated in /usr/local/lsws/domain/html/wp-content/plugins/admin-management-xtended/admin-management-xtended.php on line 110

Please fix ??
