iweb itunes podcast problem HTTP head requests

Hello!

I used iweb to build my website (www.gestecast.com) for my new podcast (i have hosting from goDaddy) Though I can subscribe to the podcast through the site, I cannot submit it to the iTunes store because I keep getting an error message "Podcast must be hosted on a server that accept HTTP head requests"

I checked with goDaddy and they said "this hosting will support HTTP head requests, however it will need to be custom coded into your application."

I have tried to research how to do this, but I'm not a developer (or even close to one) so it's really challenging. Then I found out that iWeb has been discontinued! And I wonder if this is part of the problem? Does anyone have any ideas for a solution? Should I try to find someone to add this code to my website, or should I get out of iWeb? If so to where? I really liked iWeb and have used it for years for my other website.

Anyway, I'd appreciate any help. And PS, I'm very reluctant to go with Wordpress, because I understand there is problems if you try to take your archives out of their site. And I want to have more control of my archives since these are original plays.

Thank you in advance for any advice!
