I deactivated the plugin and removed the related database tables and options. Reinstalled and it looked like a new install which was what I was after.
I have a problem with the Responsive Drag & Drop Composer however. In the header area, it does not bring over the Logo that I have set in Setting/Company Info. Although I can edit the logo in the composer screen. Should it not be using the logo as set in Settings?
Secondly, when I first loaded the Plugin and started evaluating the Responsive Drag & Drop Composer, the Header part had the Logo section on the Left and a Text section on the right (suggesting I add a latest Tweet for example). This Text Section is no longer there available for editing in the Responsive Drag & Drop Composer. If I switch to HTML view, I can see the <TD> elements where the text should be. Why can I no longer see and edit it in the Composer?
Actually, I had an idea. I entered the word “Hello” in to the <TD> tag, saved and switched back to the Responsive Drag & Drop Composer and can now see the word and the Edit control pops up on mouse-over. So, it’s seems I’ve fixed it for now.
