Rebuilding the files should make the necessary changes.
Was this ever resolved? I am having the same problem. My Comment settings are set to approve anyone, and Allow Registation is de-selected.
If I view an entry page, the form is present for a moment and then disappears. Presumably, after the JS fully loads?
After changing my prefs, I rebuilt my site and still am getting the Sign In to Comment message.
For a little more info: my templates are using dynamic publishing. After finding this thread, I then changed my Publish settings to "set individually", and set mt.js to publish a static file. Also, before republishing after the Comments pref change, I deleted my .htaccess file and mtview.php files (shot in the dark).
I would greatly appreciate any help with this issue. Thanks!
