Okay, I'm obsessed with why this works for other people but not me. I downloaded all of the updated files at sourceforge (http://pligg.svn.sourceforge.net/vie...gg/trunk/rss/). I also downloaded the latest version of magpieRSS from sourceforge (v 0.72) and replaced the files.
I've updated all the files in the /rss directory and the 3rdparty/magpierss directory with what I believe are the newest files. I'm still getting the same error. It's like it's not even trying to load the feed to get the field names.
I'm wondering if it doesn't work for some reason with my version of PHP (v 5) or if something got hosed when my SQL database was created???
