hi every,

currently i am having  strange type of problem while loading tabs

the error message is displayed as

An error has occurred.
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.Framework.DefaultPage.Page_Init(Object sender, EventArgs e) at System.Web.UI.Control.OnInit(EventArgs e) at System.Web.UI.Page.OnInit(EventArgs e) at DotNetNuke.Framework.PageBase.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---

i have no clue what went wrong with the thing. can u please suggest me probably what went wrong??

the version i m using is 4.8

well i cannot  restart application as i cannot reach host->settings as the same message is displayed for almost every tabs. but in some case some of the tabs are displayed.

Installation was working for quite a some time then suddenly i start seeing those error messages.
