RSS Feed not working.

OK. But how can i delete the empty line?

Ok, I’m closer.
I must delete empty line or space in source code.

But.. in which file or files?
i’ve checked: wp-config, wp-feed, wp-rss2 and all seem to be ok and beginning <?php and ending?> without any other bad characters….

and still nothing…

i really appreciate your help.

I’ve found error.
It was in myhack.php. There were redundant blank line.
Everything works fine after deleting it.
