Length attribute in RSS feed code

To put my podcast on itunes, I have a problem in the RSS feed code
The feed validation service check the feed and says ; length attribute of enclosure must be a positive integer

How can I change that?
Thank you!

Can you provide us with the feed URL please?


Thank you

Could you get back to me about this pb?

Looks like you have not validated your media files. Do you see the files listed and reported with a certain file size at the end of the episode page in the backend?

Also, your web server seems no to support byte ranges. This would be good to have and is needed for iTunes.
