WooCommerce problems

Hi all members

About 24 hours ago, I started experiencing an issue with my WordPress website, which is running WooCommerce.

At the moment, I am no longer receiving order notification emails when customers place an order. I am also unable to send order updates or manually resend order notifications from WooCommerce.

When I open a customer order in the WordPress admin panel, I see the following message at the bottom of the screen:

And sometimes this

And in my Dashboard I get this error

Everything was working normally before this issue started, and I haven’t intentionally changed any email-related settings.

Has anyone experienced a similar issue or know what might be causing this?

Any help or suggestions would be greatly appreciated.

Thank you in advance!
