[Plugin: Easy Contact Forms] Loading Arrows on Submit – No confirmation

I have installed ECF, created a form, placed it on a page.

However when the form is submitted the loading arrows appear to the right of the form and that is as far as we get… no confirmation that the message is sent – nothing.

The messages do seem to go through, but no confirmation is displayed to the end user.

Please if someone could point me in the right direction it would be great! 🙂
