I'm trying to display a Tumblr RSS feed in my sidebar, but it shows "An error has occurred; the feed is probably down. Try again later." This feed works with Netvibes and Google, so I know it's not down. The widget title links to the blog's URL or the individual post's.
Oddly, I'm using two other instances of the RSS widget with no problems. One of them is a Tumblr RSS as well. Both that one, and the one I'm having trouble with use custom .tk domains.
I've tried removing the working one, thinking perhaps only one was allowed, but that didn't work.
The one causing problems had items shared from the source blog. Could that cause some kind of feedback/time-out? I removed those posts, but perhaps they're still causing problems for the feed?
I don't know, just guessing. I can't think of anything about it that differs from the one that works.
The blog I need help with is teratomazone.wordpress.com.
