If you can not update buttons

[qawsed55]

I can not update buttons on toolbar.
In browser console there was error about selected.size() is not function

If you have same error you need to add code:

$(function() {
    $.fn.size = function() {
        return this.length;  }      });

before function addItem(item)
in redmine/plugins/redmine_ckeditor/app/views/settings/_ckeditor.html.erb
Reload redmine and its all done )
