Non API routes with v[0-9] are sent to the API itself, instead to the correct route.

[byCedric]

When defining a non-api route, and the url may contain a v[0-9] pattern, the route is seen as an API route.
This is a serious bug because when creating url with random variables, this can go wrong.

For example:
http://example.com/something/UnIqEev9
