postmeta #comments link no longer working

After installing this great plug in on http://www.tropicalfishsite.com I have found that the links which brings up http://www.YourSite.com/post-title/#comments no longer works.

It takes you to the post itself but does not go down to the comment section at the bottom of the post and is seen as a broken link.

Any idea how I might be able to fix this link rather than remove?

Thanks
