Logo stops appearing on other pages

ok my site is https://atomiccraft.com/ im using the Free Destro Wp theme, as you can see the logo is on, now click on a different page (except forum or hawkeye)

now the logo displays a “missing” sign as you can see.

How can i fix this?

This is the code im using on header.php
