开发者_Go百科thx.

If you can remotely access the server where it is deployed, you could try accessing your site from there, and then you can see the error, if you have customErrors="remoteOnly". Otherwise, you will need to update your web.config to allow you to see the error message (but put it back again right away, because everyone else will be able to see it also).

<customErrors mode="Off"/> 

is what you need to change it to.
