RSS Blank Line Issue

I recently installed wordpress on my website: Carlosrivera.me
setting up the feed through feedburner i received the general issue everyone has: blank line etc.

I tried everything, literally:
I installed the fix it plugin,
I downloaded the fix file wejnswpwhitespacefix.php,
I de-activated all my plugins,
I wrote string replace script for the rss2 file
I manually deleted blank lines from files like theme functions and
wp-config etc.

I also switched themes to twentyeleven, checked the validator and STILL! I’m getting real frustrated here. has anyone had this issue like me? I mean this complicated???

All of these solutions are not working and after spending 6+ hrs i just cant quit now. Is there any new info?
