PHP Warning: strlen() expects parameter 1 to be string, array given

Hi,

I have the following in my cache folder for all three of my Zen Cart test websites. I do not know what it is relating too?

PHP Warning: strlen() expects parameter 1 to be string, array given in /home/caf*****site3/public_html/caf********tsite3/includes/functions/functions_general.php on line 152

Something is not right though, otherwise I would not get this file, right? But I do not know what the error is or what I have done wrong

This is a clean install of v1.5, not an upgrade and No add-ons.

Hosting Details:
Server OS: Linux 2.6.18-274.12.1.el5
Database: MySQL 5.1.56-log
PHP Version: 5.3.8 (Zend: 2.3.0)
PHP Memory Limit: 64M
PHP Safe Mode: Off
PHP File Uploads: On
Max Size: 32M
POST Max Size: 32M
Database Data Size: 543 kB

Is it possible it is realted to this question I posted?
