"Could not find any resources appropriate for the specified culture or the neutral culture"

Cause

This error is caused when one ore more Extranet Collaboration Manager resource files do not get properly deployed by the SharePoint. To correct the problem you can manually deploy the resource files to the correct IIS Virtual Directory location. To deploy the resource files manually following the steps below. 

1. On your SharePoint Web-Front-End Server navigate to 'C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\CONFIG\Resources'
2. Copy the files 'del.resx' and 'deltempmem.resx'.
3. Navigate to the IIS Virtual Directory of your SharePoint web site
4. Copy 'del.resx' and 'deltempmem.resx' into the Virtual Directory's App_GlobalResources folder
5. Perform an IISRESET
6. Refresh your page.

This issue is caused by an error with the SharePoint deployment engine. When SharePoint deploys resources to a Virtual Directory it places them in the .NET 1.1 resource directory and not the .NET 2.0 resource directory. SharePoint does not recognize the .NET 1.1 resource location and therefore presents the missing resource error. We have spoken with Microsoft regarding this issue but they don't seem to think the need to correct this issue is urgent.

The Microsoft workaround to this problem is to perform an 'stsadm -o copyappbincontent' which is supposed to redeploy all of the resource to each Virtual Directory. We have experienced that in some situations this command doesn't always work correctly.
