PHP error/hosting error

Hi, I get this php error on my site with the plugin installed:Warning: Undefined array key “sticky-top-bar” in /customers/3/5/c/bogbrancheguiden.dk/httpd.www/wp-content/plugins/codebulls-top-bar/codebulls-top-bar.php on line 103 Warning: Undefined array key “user-can-close-top-bar” in /customers/3/5/c/bogbrancheguiden.dk/httpd.www/wp-content/plugins/codebulls-top-bar/codebulls-top-bar.php on line 104?Warning: Undefined array key “user-can-close-top-bar” in /customers/3/5/c/bogbrancheguiden.dk/httpd.www/wp-content/plugins/codebulls-top-bar/includes/generate-top-bar.php on line 8

We are having some performance issues and my host says to contact you because it is your plugin (and the error) that causes these.
Can you help?
