SMTP service response directly in page after reset password

Hi there,
we recently switched to Sparkpost for our transactional emails via SMTP. Now when I use content styling plugins like SB Welcome Mail, WP Better Mails and Better Notifications, when in the reset password page the user submits her email address, instead of the message that says that a mail will arrive shortly this happens:

The whole page code is replaced with this log (I’ve edited out the addesses), but the email is sent correctly anyway.

We have PHP 7 installed under our WordPress instance.

Any ideas? Thank you in advance.
