Installation Error

Hi!

Today I tried to install this plugin. I got an error message:

“Fatal error: Cannot declare class Leafo\ScssPhp\Colors, because the name is already in use in /[cut]/wp-content/plugins/all-in-one-wp-builder/core/helpers/scssphp/src/Colors.php on line 22”

Do you have any suggestions, what to do?

Regards,

Frank
