Hi there

I'm experiencing some errors in Umbraco Forms. Can anyone help me out? My Umbraco version is 7.1.3 and the installed version of Umbraco Forms is 4.4.4

Problem #1

In the Umbraco Forms Dashboard I get "500 Internal Server Error" from "/umbraco/backoffice/UmbracoForms/Record/PostRetriveRecordsCount"

ExceptionMessage: "Method not found: 'Umbraco.Core.Persistence.Sql Umbraco.Core.Persistence.PetaPocoSqlExtensions.OrderByDescending(Umbraco.Core.Persistence.Sql, System.Object[])'."

ExceptionType: "System.MissingMethodException"

Message: "An error has occurred."

StackTrace: "at Umbraco.Forms.Web.BusinessLogic.FormRecordSearcher.BuildSqlQuery(RecordFilter model, String select) at Umbraco.Forms.Web.Editors.RecordController.PostRetriveRecordsCount(RecordFilter model) at lambda_method(Closure , Object , Object[] ) at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>cDisplayClass13.c(Object instance, Object[] methodParameters) at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments) at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.<>cDisplayClass5.4() at System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func`1 func, CancellationToken cancellationToken)"
