Hi Maim WP,
Creating to new topic, the original topic now closed/
Looks like there is something else happening to stop the Last Purged Cachs date form updating.
Previous settings as advised have not been changed:
Optimize for shared hosting or big networks = Off
wp-config.php cURL TimeOut ini_set(“default_socket_timeout”, 600);
Mon Dec 5th, 50+ plugin updates & 50+ theme updates, all sites reporting Last Purged Cache of Dec 5th.
Wed Dec 7th, 100+ plugins, NO site updated Last Purge Date to Dec 7th, all sites still reporting Last Purge Date of Dec 5th.
