"Feed unavailable!" after moving WordPress

Hello everybody

I recently moved a running WordPress blog from one server to another and everything was just fine (after some minor changes in config files and database) until I checked my RSS feed. That was when I got the following message:

Error: Feed unavailable!

After doing a lot of searching I’ve given up and came here. Is there something in a config file related to RSS URL? Can you come up with something?

Thank you very much!
