[Plugin: Twitter Tools] Plugin not working for blog Editors

I’d like my blog’s editor to input his Twitter login and use the plugin, but he gets a blank page when he attempts to go to the Twitting Tools Settings page. I’ve tried using Role Manager to increase his capabilities, but this still hasn’t helped. The only possible way for the page to display is to make the user an Admin, which I’d like to avoid.

Is there any way to get around this, or maybe something in the code that I should be adjusting?
