Error

Hey Guys,

Really enjoying you theme so simple.

Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at [CHILD THEME FUNCTIONS]functions.php:15) in [File Path]/wp-content/themes/fruitful/inc/func/comment-inline-error.php on line 9

Any ideas what this is I have:

<?php /* Exclude Articles from Blog*/
function exclude_category($query) {
if ( $query->is_home() ) {
$query->set(‘cat’, ‘-7’);
}
return $query;
}
add_filter(‘pre_get_posts’, ‘exclude_category’);

In my child theme functions to exclude one category from the blog page.

Thanks
