Hello.

After a plugin update I get a fatal error. I tried to delete the plugin and install it from a new download. But the error still occurs.

Fatal error: Uncaught Less_Exception_Compiler: error evaluating function `fade` The first argument to fade must be a color index: 189 in /var/www/vhosts/hosting124785.a2fdc.netcup.net/httpdocs/wp-content/plugins/ameliabooking/vendor/oyejorge/less.php/lib/Less/Tree/Call.php:80
