Starting August 18th, after years of no issues, we started receiving the following error associated with Woocommerce emails:
– Mailer: SendGrid Permission denied, wrong credentials
Sample error source: WooCommerce
– /wp-content/plugins/woocommerce/includes/emails/class-wc-email.php (line: 655)
Base wordpress emails, i.e. reset password or test email via tools, work as expected.
We are running multisite with the following settings in the wp-config file:
define('WPMS_ON', true);
define('WPMS_MAIL_FROM', '');
define('WPMS_MAIL_FROM_NAME', '');
define('WPMS_MAILER', 'sendgrid');
define('WPMS_SET_RETURN_PATH', 'true');
define( 'WPMS_SENDGRID_API_KEY', 'xxxx' );
At the site level, we set the from, from name, and domain.
FYI, we’re running the latest versions of Woocommerce (5.9.0) and WordPress (5.8.2).
Are there new, specific, settings we need to include to ensure Woocommerce consumes the proper Sendgrid permissions?
