# Warning in mail-queue.php when running WP-CLI commands

 * Hi,
 * I noticed something and wanted to report it. Whenever I run WP-CLI commands, 
   I get this error printed to the console:
 *     ```wp-block-code
       PHP Warning: Trying to access array offset on null in /wp-content/plugins/mail-queue/mail-queue.php on line 500
       ```
   
 * It seems to come from the `wdm_wpma_cron_interval()` function — `$wdm_wpma_options`
   looks to be null at that point.
 * Environment: WordPress 6.9, PHP 8.x.
 * Thanks!

 * Hi boxhamster,
 * Thank you for reporting this issue. We will fix the warning regarding the `wdm_wpma_cron_interval()`
   function in our next update.
 * We expect to release this update within the next one to two weeks.
 * We hope the Mail Queue plugin serves you well and helps keep your website secure.
 * Best regards,
   Nicolas
