The problem is solved! It is in the code in the rsslib.php file. The issue was with the fopen line. The ability to open URL's as files is by default turned off on my version of php (from gentoo). I tried to do a fopen of the url from my own script, and it failed with a very descriptive error message that led me right to the problem. The part that is anoying me, is that tiki is not showing error messages in this case. I find it hard to believe that an application that has as much thought put into it as this doen't have a error log. Oh well.
