Since the update to WordPress 6.2, e-mails from the SES system do not work.
When I try to send a test email, I get the following message: “There has been a critical error on this website. Please check your site admin email inbox for instructions.” – on the website – admin.php?page=newsletter_system_delivery
Hi, try to update the SES addon to the latest version (just save the Newsletter main setting to reset the version cache). We changed the way we load the new version of the Amazon SDK that probably is in conflict with another plugin (or had a version check to strict on PHP version).
