What permissions do i need to set?

I'm installing CKEditor in my shared hosting space, and even when i simply unpack the zip file temporarily into the root of the site (where there's no access control) I get an error on the production site that isn't on the development site.

What permission do I need to set? (The hosting space is simple web space, so i have full read/write/execute permissions on it for all javascript and coldfusion, I would have thought)

Here is the link to the test install - with the samples still there so you can see the error it gives:
http://alacastinaswh.com.au/ckeditor/_s ... index.html

This link works just fine on my dev machine, with exactly the same configuration.

(When I've figured out what i have wrong, I'll fix it and move the installation behind the access control wall)

Can anyone tell me what i have wrong, and what i need to ask my sysadmin to set for me please?
