XMLHttpRequest cannot load ... No 'Access-Control-Allow-Origin'

[chessx15]

Any idea how this is going to be fixed.

From developer tool,

XMLHttpRequest cannot load http://www.chess.x10host.com/pgn4web/arena1.pgn?noCache=B72ACFD5E8.
Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header
is present on the requested resource. Origin 'http://chess.x10host.com' is therefore not allowed access.

The site is supposed to broadcast live chess games at.
http://chess.x10host.com/pgn4web/live1.html

Thanks for the help.

The browser will see chess.x10host.com and www.chess.x10host.com as two different servers. That's the way it's supposed to work. You either need to point to the same server name from your main page (so, call http://chess.x10host.com/pgn4web/arena1.pgn?noCache=B72ACFD5E8 or force a redirect on your main page to the www... version) or add an access control header to your XML page.
