ELMAH not logging errors except for 404's

除了404错误之外，我无法让ELMAH将错误记录到我的AppData文件夹中。我不确定可能是什么问题。我猜是因为我有<customErrors mode="RemoteOnly" defaultRedirect="~/Views/Shared/Error.cshtml">，但我试过做这里录制的内容，但没有任何运气。这是我的web.config（至少是使用ELMAH的任何关键内容）：

<sectionGroup name="elmah">
  <section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah" />
  <section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah" />
  <section name="errorMail" requirePermission="false" type="Elmah.ErrorMailSectionHandler, Elmah" />
  <section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah" />
</sectionGroup>
<appSettings>
  <add key="elmah.mvc.disableHandler" value="false" />
  <add key="elmah.mvc.disableHandleErrorFilter" value="false" />
  <add key="elmah.mvc.requiresAuthentication" value="true" />
  <add key="elmah.mvc.IgnoreDefaultRoute" value="false" />
  <add key="elmah.mvc.allowedRoles" value="Programmers" />
  <add key="elmah.mvc.allowedUsers" value="*" />
  <add key="elmah.mvc.route" value="elmah" />
</appSettings>
<httpModules>
  <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" />
  <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah" />
  <add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah" />
</httpModules>
<modules>
  <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" />
  <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah" preCondition="managedHandler" />
  <add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah" preCondition="managedHandler" />
</modules>
<elmah>
    <errorLog type="Elmah.XmlFileErrorLog, Elmah" logPath="~/App_Data"/>
</elmah>

这是我的FilterConfig.cs:

public class FilterConfig
{
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new ElmahHandleErrorLoggerFilter());
        filters.Add(new HandleErrorAttribute());
    }
}

和我的自定义Elmah处理程序：

public class ElmahHandleErrorLoggerFilter : System.Web.Mvc.IExceptionFilter
{
    public void OnException(ExceptionContext context)
    {
        //Log only handled exceptions, because all others will be caught by ELMAH
        if (context.ExceptionHandled)
        {
            ErrorSignal.FromCurrentContext().Raise(context.Exception);
        }
    }
}

有没有想过我可能做错了什么，或者我错过了什么？
