500 internal server error

[gr73]

Hi, I've just installed the unlimited site map generator, but when i type in [ External links are visible to forum administrators only ] I get the following message:

Internal Server Error
Directory "/websites/123reg/LinuxPackage21/co/mp/ar/compareyourtv.com/public_html/generator" is writeable by others
suPHP 0.7.1

Can anyone help?
