I would like some advice trying to debug the errors below. I am an Umbraco noob running Umbraco 7 and Courier 2.11.

I get the following when I load the locations node for my live site from my staging site in Courier.

System.Net.WebException: The request failed with HTTP status 404: Not Found. 
at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) 
at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) 
at Umbraco.Courier.RepositoryProviders.WebServiceProvider.RepositoryWebservice.GetAvailableRevisions(String username, String password) 
at Umbraco.Courier.RepositoryProviders.CourierWebserviceRepositoryProvider.GetAvailableRevisions() 
at Umbraco.Courier.Core.RepositoryProvider.GetAvailableRevisions(String folder) 
at Umbraco.Courier.UI.Pages.editRepository.OnInit(EventArgs e) 
at System.Web.UI.Control.InitRecursive(Control namingContainer) 
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

And I get this one when I try to push a revision.
