RSS Feeds not being generated

Hi There

I've been playing around with drupal for some days now. I'm quite acustomed to PHP and programming, therefore i really appreciate the flexibility drupal provides if you digg in a bit deeper, especially with templating and customizing.

I've come around to one problem though and did not find a solution for this yet, neither after searching the web or these forums.

My rss feeds are not being generated. I have quite a few modules installed (pathauto, path, views ...) i even tried to disable but no luck so far.

are not working, neither is there a

file. Does anyone have a hint i might try to fix this problem? If you need more informations, just post here.

Regards,
Peter.
