Subpages won't show!

Go to settings/permalinks and click ‘save changes’.
Do you get any messages appearing?

Nope, no messages popping up.

What happens when you view the page within wordpress admin, does it work?

Some of your menu items are going to subdomains instead, obviously you need to check that those urls exist.

It turns out I needed to update my hosted files. But now I am getting “Internal Server Errors” Links still do not work…

If you’re getting internal server errors you need to check your apache logs if you can.

All solved. Hosting company needed to update something.
