Blogengine.net asp.net exception

I was using blogengine.net and was configured to run on XML provider. But today when I opened the site, it's giving an exception.
You must reset your password using ALTER USER statement before executing this statement.
[MySqlException (0x80004005): You must reset your password using ALTER USER statement before executing this statement.]
That's weird because I'm using XML as provider and this exception is saying that I'm using SQL. I have also viewed web.config with these lines
<BlogEngine>
<blogProvider defaultProvider="DbBlogProvider" fileStoreProvider="XmlBlogProvider">
<providers>
<add description="Xml Blog Provider" name="XmlBlogProvider" type="BlogEngine.Core.Providers.XmlBlogProvider, BlogEngine.Core" />
<add connectionStringName="BlogEngine" description="Sql Database Provider" name="DbBlogProvider" type="BlogEngine.Core.Providers.DbBlogProvider, BlogEngine.Core" />
</providers>
</blogProvider>

The DLL "vsperf140.dll": the specified module could not be found

Today I made a new build of my web-application (simple aspx-web-application). When I tried to load it on my server into IIS and navigated to the startpage I got following exception:
Die DLL "vsperf140.dll": Das angegebene Modul wurde nicht gefunden.
(Ausnahme von HRESULT: 0x8007007E) kann nicht geladen werden.
(means: the DLL "vsperf140.dll": the specified module could not be found.)
also the stacktrace doesn't help me a lot:

any idea what the problem could be? Searched in google - but seems that nobody knows something about that vsperf140.dll...

From the OP in a comment:
Seems like this came with the performance profiler. Removing the project and pulling it from TFS again solved my issue.

Removed the references of AspNetHelper in web.config.
Rebuild the whole application and then deployed to new packages on my server.
(Removing the AspNetHelper in web config directly in server didn't solve my issue)

The static constructor for Product.Global is raising a NullReferenceException. This is likely due to some hard coded value that is different or unavailable on that system.
Potential candidates would be localization issues (trying to parse strings in the wrong culture) causing a value to not be initialized, a missing configuration value, or anything else that is occurring within the static initialization of that type.

Configuring Fluent NHibernate with System.Data.OracleClient

I'm trying to use System.Data.OracleClient instead of Oracle.DataAccess with Fluent Nhibernate . From what I understand, in order to achieve this I should change my driver from OracleDataClientDriver to OracleClientDriver. I've configured it like below, but I get an error that looks like it is still trying to use OracleDataClientDriver. What am I doing wrong?
FluentConfiguration configuration = Fluently.Configure()
.Database(
OracleDataClientConfiguration.Oracle10
.ConnectionString(x => x.FromConnectionStringWithKey(connString))
.Provider<NHibernate.Connection.DriverConnectionProvider>()
.Driver<NHibernate.Driver.OracleClientDriver>()
)
Here is the error, it is still looking for Oracle.DataAccess which I'm trying to get away from.

Service Stack Hello World tutorial: exception EndpointHost.Config is null

I am following the service stack "Hello World" tutorial from http://www.servicestack.net/ServiceStack.Hello/ . But when I am trying to start the asp.net application it says "Value can't be null. Parameter Name: EndpointHost.Config".
The full exception text is:
[ArgumentNullException: Der Wert darf nicht NULL sein.
Parametername: EndpointHost.Config]
[ConfigurationErrorsException: ServiceStack: AppHost does not exist or has not been initialized. Make sure you have created an AppHost and started it with 'new AppHost().Init();' in your Global.asax Application_Start()]

My global class is:
public class Global : System.Web.HttpApplication
{
/// Web Service Singleton AppHost
public class InfoAppHost : AppHostBase
{
//Tell Service Stack the name of your application and where to find your web services
public InfoAppHost()
: base("Services", typeof(InfoService).Assembly) { }
public override void Configure(Funq.Container container) { }
}
protected void Application_Start(object sender, EventArgs e)
{
//Initialize your application
var appHost = new InfoAppHost();
appHost.Init();
}
}
But it seems to never get called.
Compiling the example project from the homepage works fine - but I would like to follow the example from the homepage.
Any ideas how to solve this problem ?

I've deleted my test project and tried the tutorial once again.
When creating the Global.asax file I've deleted the whole class and made another class Global in this file. It seems Application_Start never got called in this class.

The problem as you might have guessed is that appHost.Init() hasn't run. Try wrapping it in a try/catch and logging any errors that might have been thrown.

We had the same problem and solved it by setting "Activate 32-bit-applications" to true in the extended ApplicationPool Settings. (sorry, only have a german Windows so the Settings names are rough guesses)

Took me a while to figure out what I was doing wrong to cause this issue...
this happened to me because I accidentally dragged the Global.asax file into a subfolder in my project.

I found that this error is caused by the WebApiConfig. The example is using ServiceStack and does not not need ASP.NET Web API. That line needs to be commented out inthe Gloabal.asax.cs file.
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
// ** comment out ** WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
new ProteinTrackerAppHost().Init();
}
