Need to exclude a category from main feed but allow it to work in its own feed

Hello good people,

Can your plugin: FP RSS Category Excluder

Do this:

I need to allow a category to feed in it’s own feed E.g.

http://domain.com/category/categoryX/feed/

BUT — I must exclude that feed from the site feed:

http://domain.com/feed/

I tried adding the below linked PHP to the functions.php and it keeps the categoryX feed out–but it also STOPS the categoryX feed completely!

SEE:

http://premium.wpmudev.org/blog/how-to-exclude-a-category-from-your-wordpress-feed/

function excludecatfeed($query) {
if(is_feed()) {
$query->set(‘cat’,’-categoryX’);
return $query;
}
}
add_filter(‘pre_get_posts’, ‘excludecatfeed’);

Thank you for your help!

Chris
