Instead of the default editor I use the editor WYSISWYG XHTML suite in2it. If I want to create a new item, the details are gone, are disappeared. So I can choose no category and therefore the item can not be saved. When I select the default TinyMCE editor, the details are shown to make an entry.
Question, is K2 not compatible with XHTM suite in2it or should I change something into the settings. Hope the last one, because I have not bought the XHTM editor for nothing. It's a powerful en enlarged editor ...
