well, we did pay for the domain name, does free hosting have to do with the problem? when I clicked the 'help' link, it said this:
If an XML declaration (<?xml ... ?>) appears in your feed, it must be the first thing in the feed, before any whitespace.
Unfortunately, with WordPress it seems all too easy for a plugin, a theme, or for your configuration file to contain a blank line. Further compounding this problem, some — but not all — feed readers compensate for this common error, allowing the error to go undetected for quite a while.
* Check your wp-rss2.php and wp-atom.php files for blank lines outside of <? and ?> bracketed sections.
* Check your wp-config.php file for blank lines outside of <? and ?> bracketed sections.
* Check your theme's functions.php file for blank lines outside of <? and ?> bracketed sections.
* One by one, disable plugins and revalidate until you isolate the one causing the problem.
Unfortunately, I tried all the solutions, and they did not work. Any tips?
