Hi.
I'm upgrading Dnn from 3.2.2 to the last version. Everything went smoothly until 4.9.5. Then i've upgraded sqlserver from 2000 to 2008r2 SP1, both developer edition. After this, while upgrading from dnn 4.9.5 to dnn 5.4.4 i have the following error :
System.Web.HttpException: Multiple controls with the same ID 'ScriptManager' were found. FindControl requires that controls have unique IDs. at System.Web.UI.Control.FillNamedControlsTable(Control namingContainer, ControlCollection controls) at System.Web.UI.Control.FillNamedControlsTable(Control namingContainer, ControlCollection controls) at System.Web.UI.Control.EnsureNamedControlsTable() at System.Web.UI.Control.FindControl(String id, Int32 pathOffset) at System.Web.UI.Page.FindControl(String id) at DotNetNuke.UI.Utilities.Globals.FindControlRecursive(Control objParent, String strControlName, String strClientID) at DotNetNuke.UI.Utilities.ClientAPI.GetDNNVariableControl(Control objParent) at DotNetNuke.UI.Utilities.ClientAPI.RegisterDNNVariableControl(Control objParent) at DotNetNuke.UI.Utilities.ClientAPI.GetClientVariableList(Page objPage) at DotNetNuke.UI.Utilities.ClientAPI.RegisterClientVariable(Page objPage, String strVar, String strValue, Boolean blnOverwrite) at DotNetNuke.UI.Utilities.ClientAPI.RegisterClientReference(Page objPage, ClientNamespaceReferences eRef) at DotNetNuke.UI.Utilities.ClientAPI.RegisterClientReference(Page objPage, ClientNamespaceReferences eRef) at DotNetNuke.UI.Utilities.ClientAPI.GetCallbackEventReference(Control objControl, String strArgument, String strClientCallBack, String strContext, String srtClientErrorCallBack, String strClientStatusCallBack, String strPostChildrenOfId, CallBackTypeCode eCallbackType) at DotNetNuke.UI.Utilities.ClientAPI.GetCallbackEventReference(Control objControl, String strArgument, String strClientCallBack, String strContext, String srtClientErrorCallBack, String strClientStatusCallBack, String strPostChildrenOfId) at DotNetNuke.UI.Utilities.ClientAPI.GetCallbackEventReference(Control objControl, String strArgument, String strClientCallBack, String strContext, String srtClientErrorCallBack) at DotNetNuke.Services.Install.InstallWizard.Page_Load(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
Any advice on this? My OS is windows XP SP3 professional.
Thanks
