Have you followed the Editor Quick Start videos step by step? Made sure the Editor is a top level page and not nested? File name for the page is index.php and not something else? If you’ve made sure you’ve done these things then I’ll need to see your project file in order to see where you have gone astray.
In that case provide me a copy of your project file please.
Create a ZIP file containing your project file. This is the file you open in RapidWeaver to edit your site. After creating the ZIP file, upload it using a service like Dropbox, WeTransfer, Droplr, or a similar service to create download link for us. Paste that download link in your reply.
As @DLH points out, sending it via direct message will work perfect. The caveat here though is that I won’t be able to look at until I’m back in the office on Tuesday after the 3-day holiday weekend.
