Dotnetnuke DNN站点被破坏，我可以'；无法访问任何管理选项

我正在进行DNN 6安装，由于某些原因，我的所有管理（即使是超级用户）菜单/选项都不再可访问

每次我尝试访问一个简单的菜单，如Admin>Site Settings，都会出现以下错误：

An error has occurred. DotNetNuke.Services.Exceptions.PageLoadException: An error has occurred. ---> DotNetNuke.Services.Exceptions.PageLoadException: An error has occurred. ---> DotNetNuke.Services.Exceptions.PageLoadException: An error has occurred. ---> DotNetNuke.Services.Exceptions.ModuleLoadException: An error has occurred. ---> System.NullReferenceException: Object reference not set to an instance of an object. at ArtMenuSkinObject.ArtMenuSO.Page_PreRender(Object sender, EventArgs e) --- End of inner exception stack trace --- at DotNetNuke.Services.Exceptions.Exceptions.ProcessModuleLoadException(String FriendlyMessage, Control ctrl, Exception exc, Boolean DisplayErrorMessage) --- End of inner exception stack trace --- at DotNetNuke.Services.Exceptions.Exceptions.ProcessPageLoadException(Exception exc, String URL) at DotNetNuke.Services.Exceptions.Exceptions.ProcessModuleLoadException(String FriendlyMessage, Control ctrl, Exception exc, Boolean DisplayErrorMessage) at ArtMenuSkinObject.ArtMenuSO.Page_PreRender(Object sender, EventArgs e) at System.Web.UI.Control.OnPreRender(EventArgs e) at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace --- at DotNetNuke.Services.Exceptions.Exceptions.ProcessPageLoadException(Exception exc, String URL) at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequest(HttpContext context) at ASP.default_aspx.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) --- End of inner exception stack trace --- 

关于可能发生的事情有什么线索吗

谢谢大家!

看看这个，看起来您正在使用一个名为“ArtMenuSkinObject”的自定义皮肤对象，它遇到了问题

您需要咨询skin对象的开发人员。

您最近更新了nuke吗？嗨，Mitchel，谢谢您回来。我一定要看看“ArtMenuSkinObject”对象的皮肤。谢谢你伸出援手！
