Umbraco 7未加载会员类型

Question

我已成功将Umbraco 4.11升级到Umbraco 7.1.8。一切正常，但当我尝试访问umbraco面板中的成员类型时，我收到错误。

当我在Firebug中检查错误详细信息时，它是：

{“Message”：“发生错误。”，“ExceptionMessage”：“已添加具有相同键的项目。”，“ExceptionType”：“System.ArgumentException”，“StackTrace”：“at System.ChrowHelper.ThrowArgumentException（ExceptionResource资源）\ r \ n在System.Collections.Generic.Dictionary 2.Insert(TKey key, TValue value, Boolean add)\r\n at System.Collections.Generic.Dictionary 2.Add（TKey key，TValue value）\ r \ n在Umbraco.Core.Persistence.Factories.MemberTypeReadOnlyFactory .GetPropertyTypes（MemberTypeReadOnlyDto dto，MemberType memberType，Dictionary 2 standardProps)\r\n at Umbraco.Core.Persistence.Factories.MemberTypeReadOnlyFactory.BuildEntity(MemberTypeReadOnlyDto dto)\r\n at System.Linq.Enumerable.WhereSelectListIterator 2.MoveNext（）\ r \ n at System.Linq.Enumerable.WhereEnumerableIterator 1.MoveNext()\r\n at System.Linq.Buffer 1..ctor（IEnumerable 1 source)\r\n at System.Linq.Enumerable.ToArray[TSource](IEnumerable 1 source ）\ r \ n在Umbraco.Core.Persistence.Repositories.RepositoryBase 2.GetAll(TId[] ids)\r\n at Umbraco.Core.Services.MemberTypeService.GetAll(Int32[] ids)\r\n at umbraco.cms.businesslogic.member.MemberType.get_GetAll()\r\n at umbraco.loadMemberTypes.Render(XmlDocument& Tree)\r\n at umbraco.loadMemberTypes.Render(XmlTree& tree)\r\n at Umbraco.Web.Trees.ApplicationTreeExtensions.TryGetXmlTree(ApplicationTree appTree, String id, FormDataCollection formCollection)\r\n at Umbraco.Web.Trees.ApplicationTreeExtensions.TryLoadFromLegacyTree(ApplicationTree appTree, String id, FormDataCollection formCollection, UrlHelper urlHelper, String currentSection)\r\n at Umbraco.Web.Trees.LegacyTreeController.GetTreeNodes(String id, FormDataCollection queryStrings)\r\n at Umbraco.Web.Trees.TreeControllerBase.GetNodes(String id, FormDataCollection queryStrings)\r\n at lambda_method(Closure , Object , Object[] )\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass13.<GetExecutor>b__c(Object instance, Object[] methodParameters)\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments)\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.<>c__DisplayClass5.<ExecuteAsync>b__4()\r\n at System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func 1 func，CancellationToken cancellationToken）“}

当数据库中出现重复字段时，通常会发生此问题。更新数据库时可以创建此重复。同样的情况，我将Umbraco从版本4升级到版本7.1.8。有一个名为nforum的第三方插件，它有会员类型重复问题。我通过回到原始版本（4.11）解决了这个问题，卸载了nForum插件，然后在7.1.8版本上再次更新。
