Pleas help me to solve this problem,If you know what to do also tell me HOW to do, as detailed as possible!thank you!
I have a deadline for application on the website watermillcenter.slideroom.com
but when i go it says, the following!

Server Error in '/' Application.

Runtime Error

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.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".


<!-- Web.Config Configuration File -->

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

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.


<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>

I just did a cut/paste of your url you listed in your post and I got on with no problem. Are you trying to log in on a different computer via remote access or are you using your personal computer. What browser are you using? Try a different browser to see if that works. From what I read in your post it seems to me that the server that you are trying to log in to is causing the problem and it's not on your end but that's just a guess. As to what is causing it, that can be any number of things.
