I tried sending a support request - but no response, so I'll try here:
When I added two custom fields in JoomDonation, I expected to be able to see them on the donation form. Unfortunately, they do not appear and there does not seem to be any place to turn them on other than the custom field tab. Both fields are enabled.
Here is the site: 2stayconnected.com/mirror
I can provide login details once I get a reply.
