I recently installed MT for my site, I created the site, and everything seemed to work great. Then I noticed that the commentes link was dead, and that MT was not generating a comments.html file for any of my posts. It creates Monthly Archives and Individual Archives files fine and those links work.

What have I done wrong??

MT doesn't generate a comments.html file; it uses mt-comments.cgi and the Comments Listing Templates to post comments dynamically.

Do you have a URL we can look at?
