Warnung: Invalid argument supplied for foreach() in [path]/search.php(650), help pls!

[geckoz]

Hi all,

I get an error when I'm using the search function in my vbulletin forum (version 3.7.2) but only when there are no search results:

Warnung: Invalid argument supplied for foreach() in [path]/search.php(650) : eval()'d code (Zeile 4)

How can I fix this?

This is line 650 from search.php:

($hook = vBulletinHook::fetch_hook('search_process_fullsear ch')) ? eval($hook) : false;

THanks for your help!
