If the editor is not loading, but you can see the published version of your tours/hints, it's possible that the issue is your application changing the name of the window (via window.name). In this case, we are not able to detect that you want to open the editor.
There is a workaround to this, however. You can use the following bookmarklet to open the editor in a window with your application.
Drag & drop this to your bookmarks: Open Product Fruits editor
Then navigate to your application, wait until Product Fruits is loaded, and launch the bookmarklet.
