Can't validate podcast - Artwork error
Trying to upload my first podcast....
My feed url is http://jameswdinsmoor.com/feed/podcast
The error I keep getting is "Podcast artwork must be between 1400 x 1400 and 3000 x 3000 pixels, JPG or PNG, in RGB color space, and hosted on a server that allows HTTP head requests."
I've checked and re-uploaded the artwork several times, but the error persists across multiple browsers.
I thought it might be a problem with my Wordpress site, so I tried using Soundcloud as an alternative using the exact same artwork; however a SEPARATE error comes up there "No episodes exist in your feed." But the image appears to be fine.
(That url http://feeds.soundcloud.com/users/soundcloud:users:641260389/sounds.rss)
Can anyone tell me what I'm missing?
