 When accessing the WordPress admin page, a deprecation warning is
 displayed in the error logs:

 Deprecated: strip_tags(): Passing null to parameter #1 ($string) of type
 string is deprecated in /home3/atiwpcom/public_html/wp-admin/admin-
 header.php on line 36

 This issue arises because the strip_tags() function is being passed a null
 value. As of PHP 8.1, passing null to strip_tags() is deprecated and will
 trigger a warning. The code should ensure that a non-null value is passed
 to strip_tags() to prevent this warning.
