Tertiery Background Color

Hi All! I was trying out different Colors in the "Customizer", when suddenly an Error message appeared at the top of the page: "Warning: vsprintf() Too few arguments in /home/httpd/vhosts/stadtmuur.ch/httpdocs/wp-content/themes/cath-foodmania-pro/inc/header-background-color.php on line 2799  Warning: vsprintf() Too few arguments in /home/httpd/vhosts/stadtmuur.ch/httpdocs/wp-content/themes/cath-foodmania-pro/inc/header-background-color.php on line 2801" Then I commented out these two lines and the message was gone. However after that, the hover color on the front page (title and in the Menu) are red, allthough no color is set on red. Can you help me? URL : https://stadtmuur.ch/ Thanks a lot! Kevin
