Server Error - Runtime Error

Hi all,

I have nopCommerce 1.30 running on a GoDaddy web site.  I originally installed from the GoDaddy script (ver 1.2 I think), then manually uploaded 1.30 and got it running.  It's been running for several weeks now withouth problem.  I have it installed in a /shop folder under the root and it's been quite happy there.  Today, however, I started getting the following error when accessing it:
==============================
Server Error in '/shop' 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>
==========================

So I did as suggested in the message above and other forum posts.  I edited the web.config file, replacing cutomErrors mode="remoteonly" with customerrors mode = "off".  I still get the message above though with no new details.

My store is down, so this is critical.  Any help is appreciated! Thanks.

New info:  it turns out that I could not get it to give a more specific error because I didn't capitalize the O in "Off".  Now that I did this, I get the more helpful (I hope to someone anyhow) error:

Server Error in '/shop' Application.

So now what do I do?
