 * I’ve been having an error in wp’s cron, which says the following:
 * `Scheduled action for MailChimp_WooCommerce_Single_Order will not be executed
   as no callbacks are registered.`
 * In the debug log I only have the following:
 * `[2023-04-26 01:36:31] WARNING: WooCommerce Checkout > alex*******@gm***.com 
   is already subscribed to the selected list(s)`
 * `[2023-04-26 01:37:24] WARNING: WooCommerce Checkout > alex*******@gm***.com 
   is already subscribed to the selected list(s)`
 * what can this be? By the hook, MailChimp_WooCommerce_Single_Order, I imagine 
   it is something involving the “subscribe to newsletter” field at the time of 
   purchase, at checkout.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcron-error-22%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hey [@eduardoreoli](https://wordpress.org/support/users/eduardoreoli/),
 * In the “WooCommerce Checkout” integration setting, have you enabled “Update Existing
   Users” setting? If not, please enable it and test again.

 * Hey Harish! It was off, so I turned it on. I’ll follow up to see if it will continue
   to give the cron errors. Thank you very much.
