After upgrade from Sitefinity v5.1 to v7.1, I cannot see a page previously visible. It reports 404 error. When I try to publish it in Sitefinity dashboard, it gives the following error:
Page New Line Staff page: Method 'Telerik.Sitefinity.Pages.Model.PageNode Get()' declared on type 'Telerik.Sitefinity.Fluent.Pages.PageFacade' cannot be called with instance of type 'Telerik.Sitefinity.Fluent.Pages.PageFacade'
Can anyone help me solve this? Thank you!
