Hi, I am having difficulty installing ZenCart 1.3.8a on a new web site host.

Linux, php 4.4.8, apache 1.3.41 (Unix)

I have unzipped the full install "zen-cart-v1.3.8a-full-fileset-12112007" into a directory on my site at public_html/store. As far as I can tell, I have done everything required in the initial steps of the installation instructions, setting permission on the various folders and files as requested.

When I get to the part about installation, and I enter the URL "www.mydomain.com/store/", I get a 500 Internal Server Error, and the Error Log for my site shows the following:

Code:
[Mon Apr 21 10:09:03 2008] [error] Premature end of script headers: /home/usr2001/public_html/store/index.php
SoftException in Application.cpp:238: File "/home/usr2001/public_html/store/index.php" is writeable by group
Entering "www.mydomain.com/store/zc_install/" results in the same error, and so does "www.mydomain.com/store/zc_install/index.php".

For what it's worth, my php.ini file is:

Code:
register_globals = Off

[Zend]
zend_optimizer.optimization_level=15
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.2.6
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.2.6
zend_optimizer.version=3.2.6
zend_extension = /usr/local/ioncube/ioncube_loader_lin_4.4.so

zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so
Any ideas would be appreciated....thanks.
