When tried to preview XPage in Web browser, XML source code is displayed

Hi,I created XPage in a database on local server. When I am trying to preview it in internet explorer, XML source code is displayed on one of our machines.

The I use the same database on other machine and try to preview the XPage, it is getting displayed properly.

Anything to do with the computer settings to preview the XPage in browser?

Please help.

Subject: what is the version of the server?

an older server would not be able to process the xpage.

Subject: I have created a XPage on local (not connected to any server.)

Then what could be the reason?Thanks in advance.
