Right now, there seem to be a problem in your server: http://10.34.2.230
Try to add your url to a browser and see the results.
I have no other idea about RSS and trackers..., I haven't tried this feature yet.
> I tried to set this up - which url do I use as the RSS feed? I tried http://10.34.2.230/tiki/tiki-tracker_rss.php?trackerId=1 in which I have several items. However, I get no feends (only an "empty" message, and I am using Abilon).
