Portal KnowledgeBase articles Page not Found

Hello there!

My Knowledge Articles are not showing as I enter its url.

I think I might have messed up with the web-templates. What are the things that I need to check first?

Also, does this page/viewing have something to do with "Embedded knowledge search" settings? Currently I have 2 active portals, CSS and ESS, so which of those two domain urls should I put there?

Thank you,

Rome
