I searched the forum and fixed a blank line. But still getting an error.
My sub-blogs RSS does not work and gets an error. If you go to the link you can see the error. It looks like it is still complaining about a blank line somewhere.

I ran feedvalidator and it looks fine. http://feedvalidator.org/check.cgi?url=http%3A%2F%2Ftackletog.com%2Fnews%2Ffeed%2F
Same sub-blog, but now I click on a topic, and then click on the RSS 2.0 link in the body. This works fine for per topic. http://tackletog.com/news/2009/02/15/hello-world/feed/
Running: WPMU 2.7 + Donncha's sitewide tags + Custom Header API (I removed Custom Header API so it wasn't that one) + some other hacks
Where else should I try looking for a blank line or anything else?
