Changes which may impact the "Custom CSS" setting

Hey all! We've updated the way settings work so that they're properly sanitized before your custom CSS value is added to the page.

HTML is now properly stripped from "Custom CSS" setting. Please remove any <style> tags you may have, as they are not needed and will break your CSS.

Thanks!
