    <p>I have a website that was developed using ASP.Net MVC and uses Log4net for exception logging. The website was running fine until about 4 hours ago. We haven't made any changes to the website in the last 2 weeks. The website has been running smoothly since we put it up about 1 month ago. The website is hosted at our ISP on a Shared Hosting account.</p> <p>This is the exception we are receiving:</p> <pre><code>[FormatException: String was not recognized as a valid Boolean.] log4net.Core.LoggerManager.RegisterAppDomainEvents() +0 log4net.Core.LoggerManager..cctor() +33 [TypeInitializationException: The type initializer for 'log4net.Core.LoggerManager' threw an exception.] log4net.Core.LoggerManager.GetLogger(Assembly repositoryAssembly, String name) +0 log4net.LogManager.GetLogger(Assembly repositoryAssembly, String name) +8 log4net.LogManager.GetLogger(String name) +20 i3t.LcaWeb.View.MvcApplication..cctor() in Global.asax.cs:17 [TypeInitializationException: The type initializer for 'i3t.LcaWeb.View.MvcApplication' threw an exception.] i3t.LcaWeb.View.MvcApplication..ctor() +0 ASP.global_asax..ctor() in App_global.asax.fqjmwqjv.0.cs:0 [TargetInvocationException: Exception has been thrown by the target of an invocation.] System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean&amp; canBeCached, RuntimeMethodHandle&amp; ctor, Boolean&amp; bNeedSecurityCheck) +0 System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean fillCache) +86 System.RuntimeType.CreateInstanceImpl(Boolean publicOnly, Boolean skipVisibilityChecks, Boolean fillCache) +230 System.Activator.CreateInstance(Type type, Boolean nonPublic) +67 System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) +1051 System.Activator.CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) +111 System.Web.HttpApplicationFactory.GetSpecialApplicationInstance(IntPtr appContext, HttpContext context) +215 System.Web.HttpApplicationFactory.FireApplicationOnStart(HttpContext context) +8878568 System.Web.HttpApplicationFactory.EnsureAppStartCalled(HttpContext context) +136 System.Web.HttpApplicationFactory.GetApplicationInstance(HttpContext context) +92 System.Web.HttpRuntime.ProcessRequestInternal(HttpWorkerRequest wr) +289 </code></pre> <p>The exception is being thrown in the Global.asax, where an instance of <code>log4net.ILog</code> is being created:</p> <pre><code>public class MvcApplication : System.Web.HttpApplication { private static log4net.ILog log = log4net.LogManager.GetLogger("global.asax"); public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Home.aspx", "", new { action = "Index", controller = "Home" } ); </code></pre> <p>The problem doesn't happen in testing - we are unable to reproduce it. I have deleted all the files on the live website, and re-uploaded them, just in case something could have been corrupted, but this hasn't solved the problem.</p> <p>I believe that something might have changed on the ISP side that broke something.</p> <p>Any clues on how to solve this problem?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
