SOLVED - Routing works but also gives apache 404 error

[eluser]DrDave[/eluser]
I did further checking because I have other routes defined, and none of them cause the apache 404 error, and they appear to be set up in an identical way.

For example:

Code:

$route['category/(:any)'] = "listings/display_listings/$1";

When I visit "http://www.site.com/category/automotive" it tries to GET "automotive" and succeeds - no 404. I'm totally baffled!
