ConsentFriend has five different default themes, that can be enabled in the system settings.
The scss variables have changed with version 1.3.0 in the open source part of Klaro. Sadly the changes are not backwards compatible. If you created an own theme, you have to use the new color variables. Please check the display of the consent popup after the update and after compiling the scss file for your site.
If you want to create your own theme, you could import the file
assets/components/consentfriend/scss/klaro.scssin your scss workflow. To disable the default styling of the modal afterwards, please set the system setting consentfriend.js_url to
default (or empty)
