Noitifications about security updates keeps coming after the update is done I have updated to core version 7.52 and I also ran the database updates accordingly. So why do the notifications keep coming? I have set the update check to be done once a day, and every morning I get an email that states that a security update is available for my version of Drupal. When I click the link the page opens and says that Drupal core is up to date.
I think this is the default behavior of the Update Status module, which is part of core. Unless you turn it off or reconfigure it, the modules will be checked daily and the site administrator will get email notices.
