It's not needed anymore, I found a opensesame script!

Hi Ash, copy the following code for a new aspx file ( I called OpenSesame.aspx) and put this file on the root of your site (c:\inetpub\wwwroot\YourPage) and run http://localhost/YourPage/OpenSesame.aspx) it's amazing this file!

[CODE]

<%@ Page Language="c#" AutoEventWireup="false" %>
<%@ Import Namespace="DotNetNuke.Entities.Portals"%>
<%@ Import Namespace="DotNetNuke.Data"%>
<%@ Import Namespace="DotNetNuke.Common.Utilities"%>
<%
   PortalSettings portalSettings = (PortalSettings)HttpContext.Current.Items["PortalSettings"];
   //build a query to update DB
   string sql = String.Concat("Update {databaseOwner}{objectQualifier}Portals Set LoginTabId=NULL Where PortalId=", portalSettings.PortalId);
   DataProvider.Instance().ExecuteScript( sql );
   // clear portal settings
   DataCache.ClearPortalCache(portalSettings.PortalId, true);
   Response.Redirect("default.aspx?ctl=login");
%>

[/CODE]
