Title: System Cron problem Last modified: September 8, 2025 --- # System Cron problem * Resolved [samtech456](https://wordpress.org/support/users/samtech456/) * (@samtech456) * [8 months, 3 weeks ago](https://wordpress.org/support/topic/system-cron-problem/) * I get this warning: * > System Cron Set UpNoWarning: Your WordPress site does not appear to have a > system cron job set up to run the WordPress cron. Matomo uses the WordPress > cron to generate reports and to delete temporary data to provide compliance > with various privacy regulations (e.g., GDPR). > Without a system cron job set up, these tasks may be run irregularly or infrequently, > which could lead to personal data being retained longer than allowed. * I looked into my hosting system and found this cron job * 0 0 * * */usr/bin/php /home/u555555/public_html/wp-cron.php * but it seems not enough how to fix this ?

If you have the const defined in wp-config.php, I’m unsure why that would fail.
