Re: The XML page cannot be displayed
Are your running it on Windows or Linux? If it's on Windows:
1) open php.ini,
2) search for "session.save_path" in it
3) replace the session.save path= in php.ini with c:/temp
4) save php.ini
5) create a folder in c: named temp
6) restart the server (Apache or IIS). I also had error messages about sessions and this solved it for me. HTH
