Bug found

Hi!

I’ve find a bug in DOIFD Plugin, when there are two forms to download two differents files in the same page, the “send” Buttom id and form id is the same in both.

The html of first download form is

<input name="doifd_download_form" id="doifd_download_form" value="Descargar Gratis!" type="submit">

and second download form is

<input name="doifd_download_form" id="doifd_download_form" value="Descargar Gratis!" type="submit">

and in forms id the same

<form id="doifd_form" action="/" method="POST">

and

<form id="doifd_form" action="/" method="POST">

is exactly the same id , and two forms div ids have differents names:

<div id="doifdDefault1">
<div id="doifdDefault2">

In this webpage you can see an example of the problem https://vidacoaching.es/

Thanks in advance!
