Twitter not working with Comments Plus

Like others on this forum, I can't get Twitter to work with Comments Plus. It seems to need a little more detail in the Twitter section of the settings page for the plugin, as several people have asked for help on this. I'm getting the same error others reported:

----------

Whoa there!

There is no request token for this page. That's the special key we need from applications asking to use your Twitter account. Please go back to the site or application that sent you here and try again; it was probably just a mistake.

I copied the consumer key and consumer secret from Twitter correctly, but don't see anywhere to put the request token (or even know what it is). There's a "Request Settings" section at the bottom of the "OAuth tool" tab of the app I created at dev.twitter.com, but I don't know what "Request query" to use and don't see it anywhere on this plugin's settings page.

Any idea how to get this working? You can see it trying to work at the bottom of http://jasonkelly.com.

Thank you!
