Home Page foreach fout

Hallo,

Ik heb sinds kort ineens de volgende error op mijn website staan:

Warning: Invalid argument supplied for foreach() in http://www.emoc.nl/wp-content/themes/emoc/home_page.php on line 77

Deze komt alleen voor op de homepage.
Nou ben ik een beginner als het gaat om wordpress.
Lijn 77 is waar de error begint.
Op lijn 75 begint het volgende code-segment:

<?php
