 * Hello,
   I am using Openlitespeed server with php8.1 version and installed litespeed
   plugin. I checked litespeed’s debug log and discovered this message. Can you 
   please tell me what that message is and how to fix it? Thank.
 * `PHP Deprecated: Automatic conversion of false to array is deprecated in /usr/
   local/lsws/mydomain.com/html/wp-content/plugins/xml-sitemap-feed/models/functions.
   sitemap.php on line 133`
 * code in line 133 is
 * function xmlsf_cache_get_archives( $query ) {
 *     ```wp-block-code
       global $wpdb;
   
       $key = md5($query);
       $cache = wp_cache_get( 'xmlsf_get_archives' , 'general');
   
       if ( !isset( $cache[ $key ] ) ) {
           $arcresults = $wpdb->get_results($query);
           $cache[ $key ] = $arcresults;
           wp_cache_set( 'xmlsf_get_archives', $cache, 'general' );
       } else {
           $arcresults = $cache[ $key ];
       }
   
       return $arcresults;
       ```

 * Hi, thanks for reporting the issue. It’s just a “deprecated” notice so it should
   not hurt your site(map) performance but it will be fixed in the upcoming version
   🙂
