Magento uses CRON jobs for 'automatically' updating currency rates, catalog price rules, Google sitemaps, customer notifications etc. Klevu Search plugin also relies on CRON to synchronize products. It is, therefore, very important that you setup a cronjob to execute cron.php OR cron.sh found in your Magento installation folder.
- Magento indices must be uptodate
