When I installed this plugin initially it worked like a charm. Somehow something has changed and I cannot figure out why it's not send email anymore.
We're using a combination of Gravity Forms and Formstack for forms that accept payment, but I cannot figure any conflicts between those products.
An example form is: http://www.havefunbeactive.com/free-membership/
Everything on the form works as expected... we even get the "entries" listed in the admin, it's simply not sending the emails. We have tested this on another form in our members section as well.
