U4-3860 - Unable to login after upgrading to 7.0.1

Created by Enrique Blanco 13 Dec 2013, 23:22:21 Updated by Enrique Blanco 14 Dec 2013, 08:58:47

I downloaded the final 7.0.1 version and after upgrading I cannot log into the backend. When I access the login page a get a 400 error accesing /umbraco/UmbracoApi/Authentication/IsAuthenticated

and when I type user and password I get a 500 with the following error:

{"Message":"An error has occurred.","ExceptionMessage":"No MediaTypeFormatter is available to read an object of type 'LoginModel' from content with media type 'text/plain'.","ExceptionType":"System.InvalidOperationException","StackTrace":" at System.Net.Http.HttpContentExtensions.ReadAsAsync[T](HttpContent content, Type type, IEnumerable1 formatters, IFormatterLogger formatterLogger)\r\n at System.Web.Http.ModelBinding.FormatterParameterBinding.ReadContentAsync(HttpRequestMessage request, Type type, IEnumerable1 formatters, IFormatterLogger formatterLogger)\r\n at System.Web.Http.ModelBinding.FormatterParameterBinding.ExecuteBindingAsync(ModelMetadataProvider metadataProvider, HttpActionContext actionContext, CancellationToken cancellationToken)\r\n at System.Web.Http.Controllers.HttpActionBinding.<>c__DisplayClass1.b__0(HttpParameterBinding parameterBinder)\r\n at System.Linq.Enumerable.WhereSelectArrayIterator2.MoveNext()\r\n at System.Threading.Tasks.TaskHelpers.IterateImpl(IEnumerator1 enumerator, CancellationToken cancellationToken)"}

I upgraded flawesly to some previous nightly builds, but the final 7.0.1 version is not working. Any clues?

One question about this... why the upgrade process is so different between the nightly builds and the final version? It's quite confusing
