I just build a simple .aspx page, first on my computer then run it (localhost) and nothing's wrong. but when i deploy it on a shared folder in our server, this error occurs.

Server Error in '/' Application.
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine
.
.

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

i already change the customErrors mode to "Off" but the error still persist. actually, i'm new in web programming so i really appreciate any help. Thanks in advance

i think there is a machine.config file that overrides the web.config settings. maybe you could try that?

I exactly know the solution because I had the same problem once.
The solution is veryyyyyyy simeple.
Just pu the bin folder of your application(with the dll's) in the root of your website.
