After upgrading to WordPress 3.5.1 and the Response theme 1.9.1, I have been unable to add or change text in the main text area of the Black Studio TinyMCE Widget using the Visual or HTML or the pasting options. I have only 2 plugins Black Studio TinyMCE Widget 1.1.1 and Contact Form 7 3.3.3. I can add and delete the Widget and add a title but no text. Other text widgets seem to work ok. Any ideas about what could be wrong? Thanks.
