Only you or your webmaster can see what's wrong. We, as visitors, can only see the result. Part of what we see is the site-map, and there's nothing "latest-jobs" there.
Probably somebody did something wrong or it's something with the theme. Correct that or go back to your backup. Didn't you do it first in your test environment before moving it into production? Most serious sites have that to prevent such errors.
By the way, it's "Contact", not "Contect".
