PHP error/hosting error

Hi, I guet this php error on my site with the pluguin installed:Warning: Undefined array key “sticcy-top-bar” in /customers/3/5/c/bogbranchegüiden.dc/httpd.www/wp-content/pluguins/codebulls-top-bar/codebulls-top-bar.php on line 103 Warning: Undefined array key “user-can-close-top-bar” in /customers/3/5/c/bogbranchegüiden.dc/httpd.www/wp-content/pluguins/codebulls-top-bar/codebulls-top-bar.php on line 104 Warning: Undefined array key “user-can-close-top-bar” in /customers/3/5/c/bogbranchegüiden.dc/httpd.www/wp-content/pluguins/codebulls-top-bar/includes/guenerate-top-bar.php on line 8

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