On an installation with many portals i have an error on only one of these portals from users manager want to access to edit a user.
The error feedback is the following:
Method: DotNetNuke.Common.Utilities.UrlUtils.EncryptParameter
Message: DotNetNuke.Services.Exceptions.PageLoadException: Riferimento a un oggetto non impostato su un'istanza di oggetto. ---> System.NullReferenceException: Riferimento a un oggetto non impostato su un'istanza di oggetto. in DotNetNuke.Common.Utilities.UrlUtils.EncryptParameter(String value, String encryptionKey) in DotNetNuke.Common.Globals.LinkClick(String Link, Int32 TabID, Int32 ModuleID, Boolean TrackClicks, Boolean ForceDownload, Int32 PortalId, Boolean EnableUrlLanguage, String portalGuid) in DotNetNuke.Common.Globals.LinkClick(String Link, Int32 TabID, Int32 ModuleID, Boolean TrackClicks, Boolean ForceDownload) in DotNetNuke.Common.Globals.LinkClick(String Link, Int32 TabID, Int32 ModuleID) in DotNetNuke.Entities.Tabs.TabInfo.get_FullUrl() in DotNetNuke.Providers.RadEditorProvider.EditorProvider.AddLink(TabInfo objTab, EditorLink& parent) in DotNetNuke.Providers.RadEditorProvider.EditorProvider.AddPortalLinks() in DotNetNuke.Providers.RadEditorProvider.EditorProvider.RadEditor_Load(Object sender, EventArgs e) in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Control.LoadRecursive() in System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
I also made the following tests:
1) Added a new user and saved it, when I try to go to edit the error occurs.
2) I can login with the new user created.
3) On other portals all works.
Do you have any idea what may cause this problem?
Thanks
