The RSS of my site doesn't work.
You can see the problems here: http://feedvalidator.org/check.cgi?...vil.com/rss.php

Do you have any idea of what happend?

Thanks in advance.

in my site it work´s. but the validator you posted put´s out the same errors.

script says iso, server says utf8

Try to play with these settings in lang_main_settings.php, but make tests on tests site, not on your live one, or you may get errors.
