A user here (http://themeshaper.com/forums/…..pic/prueba) added WPML support to Display Widget 1.11. However, the plugin doesn't work. I don't know whether it is because of wrong code, or that 1.11 doesn't work for the latest version of WordPress (3.0.4).
So I modified the latest Display Widget 1.14. It still doesn't work (boxes are not saved), but at least I don't have any errors (as with 1.11), and it does detect and list of all languages set in WPML. I paste below the code, and highlight the changed code. I would appreciate update of your plugin to support WPML, or at least help of what I should change below?
