I have created a page with name news, Page id is 25
Now I created a page in template with name page--node--25.tpl.php which is also working fine
I have created a view as a block with Contextual filters. and assign that block to news page
I am passing argument as
news/1 . here 1 is for contextual filter.
Now when I am accessing example.com/news/1.
It is showing page not found.
