[Plugin: podPress] Cant Activate category podcast

The URL of the category feed is http://www.flippish.com/category/happy-endings/feed/

http://www.flippish.com/feed/podcast should be the URL of the podcast RSS feed. But it does not seem to work at the moment. It is the same with the alternative URL http://www.flippish.com/?feed=podcast that is why I think this feed may have a different name or maybe deactivated at the moment.

But it could be a problem which is caused by conflict with the wp-e-commerce plugin (3.8.7.x) .
A work-a-round for this problem could be a little modification in the podpress.php file (v8.8.10.12). Modify line 300:
old (current):
add_action( ‘pre_get_posts’, ‘podPress_feed_content_filtering’ );
new:
add_action( ‘pre_get_posts’, ‘podPress_feed_content_filtering’, 7 );
By adding this number 7 (or smaller) you will give a certain action more priority during the page load. This may help until 3.8.8 of the wp-e-commerce plugin comes out.
