Hi, thanks for the plugin. I just installed the plugin (4.2) on wordpress 3.4.2 (widgets wasn't working with 3.5.1) but when I use the add image, video buttons or add smileys it just shows an empty popup. Already tried emptying browser cache (FF) and tried the same on other browsers (chrome and ie10). Uninstalled and reinstalled the plugin. Checked the support forum here and on your site. None worked. Thanks in advance for your help.
