I was plagued with this problem as well and found a working solution here: https://www.kriesi.at/support/topic/rss-feed-not-working-anymore/

The important bit:

Tried this in wp-content/plugins/nextgen-gallery/non_pope/class.photocrati_resource_manager.php

function print_marker()
    {
if(is_feed()) return;
        print $this->marker;
    }

Seems to work.

Sabinou,

Thank you! Using both definitions worked perfectly in my case. It was neither a plugin or theme issue.

Adding more information to hopefully guide others in finding this: I’m getting 7 javascript errors on the wp-admin/post-new.php and wp-admin/post.php pages.

They are as follows:

nope, omitting the depth parameter changed nothing. Ideas? Could a plugin be messing with the wp_list_pages template tag?
