Multisite Blog post ans custom post are showing page not found

Hi,
I have installed mutisite and everything is working fine except blog post and custom post. I have found some solution in a forum that make permalink /%postname%/ but i did accordingly no luck. Same issue page not found. You can check the blog post and portfolio post is not working properly.
