Error after submission - newsletter subscribe

[Tonyy]

Hi
I installed the newsletter subscribe contribution , looks good and works fine , sends the emails and updates the data, but after I click on subscribe , I get the thank you page with the below error at the top of the Thank you page.

The subscriber email gets the email and the address is added to the list of subscribers,I am using PHP mailer, zen 138a and the mail is functioning normal.

No error is showing in the cache.
