Hello everybody,

I get a critical error after clicking on Admin>Site Settings (Host portal and also on other parent portals!)

That happened after I deleted all folders from a "parentportal/users" folder! (Had to fix a BOT attack)

Since then I can't access "Site Settings" page of any of my portals. For some reasons, the folders that I deleted, they somehow appeared again (have been regenerated again! Even if I deleted all the users from the DB, by clicking "Remove Deleted Users")

Below the  the stack trace 

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.ExtensionPoints.UserControlExtensionControl.LoadControl(IUserControlExtensionPoint extension)    at DotNetNuke.ExtensionPoints.UserControlExtensionControl.OnInit(EventArgs e)    at System.Web.UI.Control.InitRecursive(Control namingContainer)    at System.Web.UI.Control.InitRecursive(Control namingContainer)    at System.Web.UI.Control.InitRecursive(Control namingContainer)    at System.Web.UI.Control.InitRecursive(Control namingContainer)    at System.Web.UI.Control.AddedControl(Control control, Int32 index)    at System.Web.UI.ControlCollection.Add(Control child)    at DotNetNuke.UI.Modules.ModuleHost.LoadAjaxPanel()    at DotNetNuke.UI.Modules.ModuleHost.CreateChildControls()    at System.Web.UI.Control.EnsureChildControls()    at System.Web.UI.Control.PreRenderRecursiveInternal()    at System.Web.UI.Control.PreRenderRecursiveInternal()    at System.Web.UI.Control.PreRenderRecursiveInternal()    at System.Web.UI.Control.PreRenderRecursiveInternal()    at System.Web.UI.Control.PreRenderRecursiveInternal()    at System.Web.UI.Control.PreRenderRecursiveInternal()    at System.Web.UI.Control.PreRenderRecursiveInternal()    at System.Web.UI.Control.PreRenderRecursiveInternal()    at System.Web.UI.Control.PreRenderRecursiveInternal()    at System.Web.UI.Control.PreRenderRecursiveInternal()    at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)    --- End of inner exception stack trace ---

Any suggestion? 

Thank you
