Post does not show in my blog page but does in my homepage

I have a problem with my blog page. Whenever I create a new post you can see it and that blog page and see the post title and some of the description but if you click on it it says page not found, I have my Permalinks set up as ( Custom Structure /%postname%/ ) and if I put the same/%postname%/ under Category base. It will show all the post information only in the front page as recent post but if I go to the blog page it’s empty and it says page not found. Can anyone help me fix this please.
