If you've manually edited any of the files in your /conf/ folder you might like to check them for whitespace

seems like i don't have the problem today - maybe there was something that my other browser didn't like?

The reported problem exists. It´s the same that I get in my blog:
http://www.suzukign.com.ar/blog/blog4.php?tempskin=_rss2

Any help?

I Don´t make any change on any page. It´s the complete downloaded version.

I tried with an english empty blog and the error is the same.

The generated XML appears to be ok. (at least, compared with other working sites)

Solved!!!

I replace the next folders:
-Install
-Inc
-skins
-skins_adm

and re run install with the UPDATE option selected.

That fixes the problem.

The strange issue is that, before the update, in IE6, the complete XML of the rss were shown, but with an empty line on top. That corrupts all the file.
