 * Hello,
 * I just updated one of my sites from PHP 8 to 8.1, and the log is constantly filling
   with the following 2 notices:
 * `Deprecated: strpos(): Passing null to parameter #1 ($haystack) of type string
   is deprecated in /home/site/public_html/wp-includes/functions.php on line 7241
   [](https://www.shelleyfoster.com/wp-admin/index.php?elm-log-cleared=1#)[](https://www.shelleyfoster.com/wp-admin/index.php?elm-log-cleared=1#)`
 * `Deprecated: str_replace(): Passing null to parameter #3 ($subject) of type array
   |string is deprecated in /home/site/public_html/wp-includes/functions.php on 
   line 2187`
 * The notices disappear when I deactivate this plugin. Any idea on what is causing
   this and how to resolve it?
 * Thanks!
   Sarah
