Won't save tokens

I’ve been trying for a week now and can’t get it to connect to Twitter. It doesn’t seem to save the tokens. When I go to edit, they are blank. I have no problem with other plugins that do this.

Here is the message I get on the second link click to authorize it:

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.
