Twitter keeps blocking our plugin. You will need to ask for your own API key at twitter.
@ednong this is a new issue with Twitter that results due to a Spam Protection Protocol that suspends the b2evolution API key.

As @fplanque suggested, get your own api ket from Twitter, then try again. Would be nice if you can let us know if this resolved the issue.
