Default Server Error in '/' Application - Runtime Error

Hi all,

I am FTPing a test site I have created in Visual Web Developer following the book.

I can get the site FTPed ok, but when I run it in a browser from the remote server at Netcetera I get the following error! Any thoughts as to why?

Code:
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>

Hard to say, as the real error is hidden. Could be anything from a web site configured for .NET 2 (my guess of the problem), to file permissions, database issues and more0. Your host should be able to figure out what the problem is by looking into Windows Event Viewer.

Cheers,

Imar

If I upload a simple aspx page with no sql control on the page then it runs fine as seen here: www.essentiaclientmanager.com/default02.aspx

But I would guess that it has something to do with the SQL controls linking to a database...

Is there something that I should be doing in respect of the database aspect of the website before moving it to the remote server?

If I try http://www.essentiaclientmanager.com/default02.aspx I get an error as well.

Did you try setting customErrors to false?

I have added the custom errors element to the web.config. The page now shows the error:

Sounds like you set up the site to use SQL Server Express. Does your host support that? Did they give you a connection string? They should be able to provide you with the details about setting up the database correctly.

Cheers,

Imar

Yes they do support Express but they haven't given me a connection string... I'm finding it quite difficult dealing with them....

Right. I finally have a connection string.


Data Source=sql1096.netcetera.co.uk;Initial Catalog=YOUR DATABASE NAME HERE;User Id=YOUR DATABASE USERNAME HERE;Password=YOUR DATABASEsomepwd

Where do I put this?
