I got the same thing.

I’m guessing ‘template\_route=’ is deprecated in Rails 2 - I assume you  
are using version 2?

change ‘template\_route’ to ‘view\_paths’ on line 5 of vendor/plugins/  
routing\_navigator/lib/routing\_navigator\_controller.rb

You will also need to change ‘start\_form\_tag’ to ‘form\_tag’ on line 13  
of vendor/plugins/routing\_navigator/views/routing\_navigator/  
index.rhtml

That worked for me. I’m not actually sure if it does the ‘right thing’  
but it looks about right!
