What does “Your batch has been queued.” mean? When will my import job be processed?
After you perform an import using the Import Wizard, you will likely see the message: "Your batch has been queued." This means that your records have been parsed from your input file (or Active Directory / LDAP connection), and will be imported in the background shortly. Importing your records in the background in this manner keeps your import jobs from being interrupted or timing out.
You can check on the status of your job in the Import History tab. If you feel that your batch is stuck, this most likely means that your website has disabled WP Cron. You can verify this by editing your wp-config.php file and looking for the following line:
define('DISABLE_WP_CRON', true);
To get your import job running, visit the URL https://yoursite.com/wp-cron.php in your browser (replace yoursite.com with your own website's address). This page will most likely display a blank white screen, but that doesn't mean its hasn't worked. Refresh this URL 3-4 times in your browser, and then verify that your import has started by visiting the History tab. If it hasn't, try refreshing the wp-cron.php URL again in your browser.
You can address this long-term by scheduling a cron job on your system to trigger WordPress' own WP Cron system. This will ensure that all jobs scheduled with the WP Cron system fire when they should, which will benefit all of your plugins.
