404 page going to listing entry template only in first segment

Question

I can only trigger the 404 template for anything more than two segments, for example, if this is bad link I see 404 page: site.com/wrong/link

When just accessing one segment like this for example, site.com/wrong page displays my listing entry template outputting same entry.

Here's template...maybe something on there or route that isn't set up correctly?

Here's my route setup:

Answer 1

Still not entirely sure from your question what you are trying to do, or how the template excerpt helps, but just for clarification, the template route in the screen grab will capture any URL that happens to begin /blog/something - regardless of whatever follows it (provided the second term matches the alpha_dash character list).

Unless you have some other route set up, there appears to be no way that you can get a 404 to display for any URL that happens to begin /blog/somethingas the template route will grab these and send them to your blog-entry template.

Maybe you should think about changing the template route status for Segments Required? to yes - this will not change the route behaviour for /blog/something but will not intercept urls with more terms (so /blog/something/else wouldn't be captured by the route if you change the segments required flag.
