Edit Data Mode won’t work

Dear Michael

I have a new homepage where I want to enable my Edit Data Mode Plugin.
I have to say that it is the second page I installed it, but it’s because this page will replace the page where I’m using it now.

I activated the CFDB Plugin and the Editor Plugin. But the following Error will appear and the Edit Data Mode won’t work:
Error: plugin “Contact Form to DB Extension Edit” requires that plugin “Contact Form to DB Extension” to be installed and activated.

Thanks in advance for your help.
