HI, @cakru
There are several potential causes for this issue. To start, double-check the email settings in your WooCommerce settings to ensure the correct email address is being used for the from address and that the SMTP settings are correctly configured. Additionally, verify that the email address associated with the account the user is attempting to reset the password for is valid and not blocked by any spam filters.
It’s also possible that there is a compatibility issue between the Ultimate Member plugin and the version of WooCommerce you are using. Try deactivating Ultimate Member and see if the problem persists. Additionally, check the configuration of your email server, as some servers may have blocked outgoing mail, or the IP address of your server may be blacklisted.
You can also review your website’s error log to see if there are any error messages related to the lost password email sending. Also, contact your hosting provider to ensure your server has permission to send emails.
Thank you.
