your scripts arn't running? What language are they running in? As far as i can tell, only python and perl are supported.
For versions, you can look here: http://com.x10hosting.com/test.html
assuming that x10 has the same versions installed on all the servers.
It helps if you give a link to one of the pages that does not work rather than have us blindly look around your site.
1. Uploaded file in ASCII mode or binary (especially if script came from a Windows machine)?
2. Permissions set and path to Perl correct?
3. If you show us the code, we might be able to spot any errors.
