Submission Takes Forever

First of all let me thank you for putting up an amazing plugin. Although Contact Forms looked easy to me when I began I realized recently that it is not. This is I believe the third and the last plugin I shall use to put my Contact Form to work. This one was easy and in no time it was up.

Now the problem is after filling up the details, solving the reCaptcha when I hit the the Submit it takes forever. However the unpublished version seems to be working without any problems. I am afraid I feel irritated about Contact Forms now. Or is it to do anything with the Google’s reCaptcha.

Any help will be angelic.
