 * I wanted to report that the plugin is not fully compatible with PHP 8.3. Upon
   running it in a PHP 8.3 environment, the following warning is generated:
 * **Deprecated**: strpos(): Passing null to parameter #1 ($haystack) of type string
   is deprecated in **/var/www/csi/html/wp-includes/functions.php** on line **7329**
 * **Deprecated**: str_replace(): Passing null to parameter #3 ($subject) of type
   array|string is deprecated in **/var/www/csi/html/wp-includes/functions.php**
   on line **2189**
 *     ```wp-block-code
       Deprecated: rtrim(): Passing null to parameter #1 ($string) of type string is deprecated in /var/www/csi/html/wp-includes/formatting.php on line 2819
       ```
   
 *     ```wp-block-code
       admin\class-admin-asset-dev-server-location.php:  56    57:       if ( strpos( $version_less_source, 'select2' ) !== false ) {  58            return $this->get_default_url( $asset, $type );admin\class-admin-init.php:  118   private function on_wpseo_admin_page() {  119:      return $this->pagenow === 'admin.php' && strpos( filter_input( INPUT_GET, 'page' ), 'wpseo' ) === 0;  120   }  340   private function has_postname_in_permalink() {  341:      return ( strpos( get_option( 'permalink_structure' ), '%postname%' ) !== false );  342   }
       ```
   
 * This issue seems to be related to deprecated functionality or compatibility issues.
   It would be great if the plugin developers could investigate and update the codebase
   to ensure compatibility with PHP 8.3.
