Editing file XYZ.css: File XYZ.css is not writable

I'm not sure how your server/ftp is set up but if your user has no write access to that file then you'll need to give it access. set the permission on the file to 666 and that should fix it.

If you are trying to write to these through your admin panel you cannot. You must actualy enter into the css files through your Cpanel.

find the css files on cpanel and chmod them to 666, and they will be writable from within the admin panel on dolphin

Wow the repetitive people on Unity.
