I've been very happy with Gravity Forms, it's a fantastic solution for my wordpress site. Mostly I have no problems at all. However, I recently had a user who submitted a form. The form was received just fine, with the only problem that he input his own email address incorrectly on the form. No biggie, right? But now for some strange reason, I receive the same form he submitted (with the wrong email address in it) again. Automatically. Once or twice a day.
I confirmed with him that he only submitted the form once.
Is this a known issue? Is there any way to stop Gravity Forms from automatically sending me the same previously submitted form over and over again? The only strange thing I can think of is that the email address is incorrect (it's in the valid format of abc@abc.com, but it's just not a correct email address).
Other people have been submitting the form just fine but it's only that one particular form that continuously resubmits itself.
