20203	To return 404 page when user request not existing category and existing at once (in URL)	egorpromo		"I have category 'category1' with posts in it. I want to get posts from 'caegory1' and not existing category 'not_existing'.
if I use URL like 'http://mysite.com/category/category1+notexisting' I get normal archive page but this is a page without post because there are no posts in 'category1' and 'not_exists' at once.
But maybe it is better to return 404 page? Because it produces additional duplicate pages for search engines like google."	enhancement	new	normal	Awaiting Review	General	3.3.1	normal
