I have this plugin installed in my website. I have a contact form with some dropdown menu options.
But, when my visitors click on the 'Send' (or Submit) button at the end of the contact form, it does not show any message showing success. That way, my visitors get confused and they keep clicking on the button that results in multiple emails in my inbox at a time.
Here is my contact form: http://hghsuppliers.com/buy-hgh
