[Plugin: WP RSS Aggregator] Bug in version 2.2: wprss_feed_source_order assumes everyone is an admin

As written, the function below (inc/custom-post-types.php:143) assumes that all users are administrators:

function wprss_feed_source_order( $query ) {
        if ( ! is_admin ) {
            return;
        }

        $post_type = $query->get('post_type');

The error is a result of omitting parentheses on the call to is_admin.

I’m not sure how serious it is that any user can potentially alter this ordering.

PS – do you develop with notices enabled?
