404 errors on all my pages!

Help
If you go to my website at https://www.saferoofcleaning.com and click the menu, ALL my pages except the home page display the 404 error.
What is wrong ?

Hi,

It looks like you were already able to solve your issue.
I’ve checked your site and I can access pages I’ve clicked from your top nav. And no page that shows 404 errors.

Regards,
