Hi I am getting this error with the latest version of wordpress, cforms2 and your plugin:
This text only appears to users able to publish pages or posts. There is no CFormsII data that matches the values in your shortcode. Try starting with [cformstable display='table'] to see a list of possible forms you can report from.
I have tried another plugin but its not working, the code I put into the page was: [cformstable display='table' form='Note_second']
Am I doing something wrong?
