Tag links fail to find tagged discussions
I've got the "Tagging" plugin enabled (v. 1.1p1 on my v. 220.127.116.11 Vanilla site). The tags are created, can be seen in my admin dashboard, and get correctly listed in the sidebar of the site ("Popular Tags", with number - I'm using the default theme).
The trouble is: clicking on the tag link in the sidebar gives a "No items tagged with [tag]." message. But there are items tagged!
Can anyone help me troubleshoot this? I've search the community forum, but haven't been able to find this problem reported before.
