I installed version 1.1.8 of the Contour package to a site and added a license file but am having problems creating forms.

When I create a new form the form does not seem to set up correctly. I get no error messages (on screen or in Firebug) but the "Forms" node in the tree does not refresh and the Designer tab is empty. See the screenshot...

This happens regardeless of whether the new form is based on a template or is blank.

If I try and save a change to the form settings I get an on-screen error "Failed to save form" and in Firebug I can see a 500 error for the page /umbraco/plugins/umbracoContour/Designer.asmx/Save

The reponse of this ajax call is:

{"Message":"Invalid web service call, missing value for parameter: \u0027manualapproval\u0027.","StackTrace":"   at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary`2 parameters)\r\n   at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n   at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

I have tried uninstalling the Contour package and re-installing but this doen not solve the problem.

I have other sites on the same server using this version of Umbraco and Contour with no issues.

Any help would be very much appreciated.

Thanks.
