why is this not a valid feed? what do i do?

Try giving feedburner a real URL: https://audacify.com/feed/ (instead of one that starts with “feed://”)

feed://audacify.com/feed/

that doesn’t work either

Why not? If you give the validator an ‘https://’ address as Chris_K said, it validates. It actually validates with the feed prefix too if only because the validator converts the ‘feed://’ to ‘https://’.

oh durr, i misread Chris. i followed your guys’ advice and it worked! thanks much!
