I keep getting the ...."error with feed" msg, but I believe it's related to the feed I'm trying to display, not the plugin. Here's the shortcode I'm using:
[RSSImport display="3" feedurl="http://livewelljacksonhole.com/feed/" before_desc="<p class='desc'>" after_desc="</p>" displaydescriptions="true" truncatedescchar="80" error="Sorry, there has been an error with the feed."]
If I substitute that particular feed with another feed, it works! Also, if I run this shortcode from my localhost it works. Do you have any idea what might cause a feed to fail?
