Blank Popups

Hi! I’m using latest version of plugin and wordpress, and I’m getting a blank popup.

Getting this error in firebug when clicking image button:

Error: Permission denied to access property 'tinymce'
tiny_m...ver=358 (línea 5)

TypeError: tinyMCEPopup.editor is undefined
mctabs.js?ver=358 (línea 13)

TypeError: tinyMCEPopup.editor is undefined
form_u...ver=358 (línea 11)

TypeError: this.params is undefined
tiny_m...ver=358 (línea 5)

Thanks.
