Error in xpage

Hi,

Anyone, plz help me about the errors of my program.

I am now using xpage. But the project can run on IE in my machine.

When i upload the server, my project can’t run.

I can saw the home page. When i click the link,

the error is shown like that.

• The website is under maintenance.

• The website has a programming error.

The difference is " before i upload the server, i change the project name(Rename)".

Plz help me for this error. Thanks
