[Plugin: Contact Form 7] error message

I am getting this written across the top of my admin dashboard.

Warning: array_key_exists(): The first argument should be either a string or an integer in /hsphere/local/home/c262876/barelycivilized.net/wp-content/plugins/contact-form-7/includes/capabilities.php on line 14 Warning: array_key_exists(): The first argument should be either a string or an integer in /hsphere/local/home/c262876/barelycivilized.net/wp-content/plugins/contact-form-7/includes/capabilities.php on line 14 Warning: array_key_exists(): The first argument should be either a string or an integer in /hsphere/local/home/c262876/barelycivilized.net/wp-content/plugins/contact-form-7/includes/capabilities.php on line 14

Any ideas what to do to fix it
