Template mailchimp removed code by phplist

hi!

I have a hard time to get the following template working (not as send a webpage option) but as pasting into compose message with under tools - source code and past in the html

the template https://github.com/mailchimp/email-blueprints/blob/master/templates/fancy-1-2-3.html

phplist removes code of the message so it does not work correctly, does anyone point me into a direction how to solve this?

thannks!

You need to use CKEditor, not fckeditor, and on the Settings page ensure “Allow templates to be edited as full HTML pages” is set to Yes.
