HTTPS causes issue

Now that the email field is fixed, I have another issue (sorry)

When I choose the configuration parameter "use HTTPS", the donation form comes up fine in the module, but when I click "Donate", the website times out. If I uncheck "Use HTTPS", it seems to work just fine.

Do I need to get a secure key for the domain to use https? (sorry if this is an elementary question. This is the first payment system I've implemented.)

Hi
To enable https , your site must support https . You need to purchase a ssl cetificate for your domain . If your site doesn't support https , you cannot enable https in Joom Donation .
Thanks ,
