Hi,

For the past 3 days, I have been getting a Critical Error displayed in the first module on the Page displayed to users immediately after login. The Crital Error is:

Message: DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object.
 ---> System.NullReferenceException: Object reference not set to an instance of an object.
 at DotNetNuke.Common.Utilities.XmlUtils.GetAttributeValueAsInteger(XPathNavigator nav, String AttributeName, Int32 DefaultValue)
 at DotNetNuke.Common.Utilities.Config.GetPersistentCookieTimeout()
 at DotNetNuke.Entities.Users.UserController.UserLogin(Int32 portalId, UserInfo user, String PortalName, String IP, Boolean CreatePersistentCookie)
 at DotNetNuke.Modules.Admin.Authentication.Login.ValidateUser(UserInfo objUser, Boolean ignoreExpiring)
 at DotNetNuke.Modules.Admin.Authentication.Login.UserAuthenticated(Object sender, UserAuthenticatedEventArgs e)
 at DotNetNuke.Services.Authentication.AuthenticationLoginBase.OnUserAuthenticated(UserAuthenticatedEventArgs ea)
 at DotNetNuke.Modules.Admin.Authentication.Login.cmdLogin_Click(Object sender, EventArgs e)
 at System.Web.UI.WebControls.Button.OnClick(EventArgs e)
 at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument)
 at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument)
 at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)
 at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)
 at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
 --- End of inner exception stack trace ---

The login actuallly proceeds OK and when the logged-in user navigates anywhere, the error is not encountered again. In other words, it only occurs on Login.

In trying to locate this error I assume the method:

 at DotNetNuke.Common.Utilities.XmlUtils.GetAttributeValueAsInteger(XPathNavigator nav, String AttributeName, Int32 DefaultValue)

is not being passed a valid parameter.

Is there some way I can debug this or has someone discovered a way to fix this error.

Thank you.

I am getting the same error and cannot figure it out.
Error started after XL module update as specified before 5.2.2 update, XML module was supposed to fix this before upgrade = user profile's ability to change and I get a error thus not being able to change profile settings or authorize user, login works but error on home page.
I wish DNN staff would address this?
