RSS feed problem

Hi All –

A few visitors to my site have mentioned that the RSS feed isn’t working properly, and pointed out that there is an empty line at the start of the rss feed:

I’m admittedly a blogging novice — which file(s) would I have to edit to fix this problem? Any expert help would be appreciated. ??

Thanks –
