Can't get my /. submission RSS feed to work in Drupal.

Hello.

I cannot seem to get Drupal to correctly show my /. submission RSS feed at
http://slashdot.org/firehose.pl?op=rss&content_type=rss&view=usersubmiss... ... On http://aqfl.net/ it doesn't show any stories. According to http://www.aqfl.net/?q=aggregator/sources/23, it shows http://slashdot.org/firehose.pl so it seems like paramters got cropped off even though configuration shows the whole URL):(

I don't know what Drupal version (it's years old for sure) my friend's host server is using (I am not the admin.). Is there a way to check?

Thank you in advance. :)
