Okay, finally sorted it. Here's how I fixed it...
1. Changed template to Responsive in Admin/Tools
2. Uploaded the Flexible Footer mod and installed it over the existing Wesminster template
3. Activated the Footer mod - Yay, it worked!
4. Reinstalled the Westminster template Flexible Footer Files.
5. Changed the template back to Westminster and Voila... I have a footer and a happy website.... so far!
The instructions don't mention about downloading and installing the Flexible Footer Mod before installing the template... it's mentioned afterwards, and that didn't work for me as a fresh install.
