Hello,
I've got the same problem with CB installation.
The problem is probably not connected with file and directory permissions but with compatibility php version and/or system. Please note that I was able to install other components, templates, and modules.)
Here is my system information.
Shared Windows 2003 server
PHP Version 4.3.1
MySQL 4.0.23-nt
I tried patching it with safemode patch (Guess, this is just for unix system) and even tried installing CB through the directory but all failed.
Pls. help. Thanks.
