Problems feeding my XML feed at Meta Commerce

Hello,

I’ve already created my Feed for the Facebook Business Commerce Catalogue. Everything is set, but at the feed page, the feed is not possible. The information at the feed page is that the feed format should be in a correct XML file other wise it won’t be supported.

When creating the feed, you only have 1 XML type. That was the file type I choose but it seems it’s not working.

Can you help?

Thanks very much!
