I ugraded my site to WP3.0.
Now, on Google Chrome, at the end of each post, it shows "No Tag". If you use this browser you can see it on http://www.okey.ro.
I don't see this message on Firefox or Internet Explorer.
The tags are set ok on each post.
This sentence shows on most of the themes I tested.
Can't find where the code is located, there is no "No Tag" on template itself.
