Hi
I'm not sure what the problem is but the issue is not related to Datafeedr.
If I view a non-dripped post which also has tags, clicking on those tags does not work. For example,
http://www.totallyt-shirts.com/2008/...eling-service/ is a non-dripped post but when I click on one of the post's tags, I also get the same "not found' error.
I even deactivated Datafeedr and the tag links still do not work.
I would check your other plugin settings and your configuration of WP.
