Hi, I have the latest versione of wordpress (3.5.1) and of your plugin (1.4.8) and I am using Thersus Theme v1.3.4.
The problem is that, only in the home page, in the admin panel, in the visual mode I don't see anything, and I can't switch to text mode.
Another problem is that in the widget menù, always in the admin panel, I don't see the right coloumn, that in which there are the widget in use, and not even the one in the bottom of the page, that in which there are the widgets not in use but that mantain the settings.
All this problems disappears when I deactivate the plugin.
The frontend, instead, don't show any problem.
