coffee_king on "[Plugin: Custom Contact Forms] Successful Submission Message not displaying?"

Hi there
For some reason with [Plugin: Custom Contact Forms] the Successful Submission Message is not popping up on the screen/displaying after the SEND MESSAGE button is pressed?

I am getting the emails through OK, but the person that is sending the emails isnt getting confirmation that the form has been sent at all.
(the form then resets itself)

Any help?
