Recover Posts

Hi,
Needed help i successfully move my site from former hosting to a new hosting from the backup. But now my problem is I cannot view all posts. once i click the posts it says “Not Found -The requested URL /post-name/ was not found on this server.” which if i go to admin panel and check to edit my posts it is there. but in publish it is not there…

What do i need to do to recover my old posts and function my site running again..

This is My Site

Thanks in Advance
