Hi,
I checked your site (team, contact pages) and don't see any 404 errors. 

But if you are still experiencing issues, here is what you can try:
Go to Settings -> permalinks and just click save.
This will regenerate .htaccess file on your server and set WordPress URL handling in order.

If this doesn't help, then please share your username and password (privately) and I will check and see if I can resolve the issue.

Kind regards,
Andrej
