All The Listings Links Are Suddenly Broken

All of the links on my website are broken. They were previously working fine. I checked the links, and they look fine, but none are working.

What could have caused this?

How can I fix it?

Hi,

Please try refreshing your permalinks. If it doesn’t help, please provide us with more details. When did the links stop working (after what)? Maybe you installed some third-party plugins?
