 * Hi,
 * We receive this php error in our debug log whenever a page is 404 using this 
   theme:
 * > [02-Dec-2025 19:15:14 UTC] PHP Deprecated: strlen(): Passing null to parameter#
   > 1 ($string) of type string is deprecated in /sites/website/files/wp-content/
   > themes/rife-free/header-variants/horizontal-one-line.php on line 30
 * Each time we upgrade the theme, I have to go in and add an isset($show_header_at)&&!
   empty($show_header_at) check on the line, before using strlen, to quiet this 
   error.
 * If this could be patched, that would be great.
 * Thank you.
