Pages not showing

Migrated site.
The homepage shows up, but other menu pages do not. When I click on something other than “home” it gives me a 404 error.
I check my pages and they are there but I can’t get to show on the menu, even when I re-add them to the menu.

Also if I go to pages and view page its a 404 error. But If I edit the page it shows fine.

The page I need help with: [log in to see the link]
