With the new WordPress 3.9 update, ZipList has caused a major issue on the site I was working on (http://fabulesslyfrugal.com). When the plugin is active, the posting area does not show text or images. It's blank, and you cannot click inside it to edit. It doesn't work in either the Visual or Text mode. When we disable the plugin, the problem is solved. Can you let us know if there is a ZipList update that will take care of the problem?
