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">

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)

Lost uCommerce interface within Sitecore

I am developing a web application using SiteCore 8 and uCommerce. To configure uCommerce I go through Sitecore and load the uCommerce interface. This morning I tried to load the uCommerce interface in the normal way, i.e logged into Sitecore and loaded uCommerce, but got nothing more than a white screen in Sitecore. Looking at the browser console I can see 2 different 500 errors:
Failed to load resource: the server responded with a status of 500
(Internal Server Error)
http://local.myapp.co.uk/ucommerceapi/Content/undefined/RootNode

(Internal Server Error)

load resource: the server responded with a status of 500 (Internal

If I click on the url in the error I get a page that displays:

I have tried recreating the Global.asax, I have tried replacing all the sitecore folders:
sitecore
sitecore modules
sitecore_files
and the App_Config folder using files from a colleagues machine that is working fine but not luck. I can copy my colleagues solution to my PC and it works fine (except he has none of the work I have done)
Can anyone throw any light on what the problem might be?

In case anyone else stumbles on this problem. I deleted the website from IIS then recreated it and the problem has gone away. I have no idea why this has fixed the issue, as I have changed nothing in IIS for days.

MVC Application - Retrieve the LoaderExceptions from Global.asax.cs

I am getting the following error when trying to implement code from my peers:
Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
I see there is a posting for how to "How to retrieve the LoaderException property?" here (How to retrieve the LoaderException property?)
But, I do not understand where this try catch should go since the code to implement my peers code is in the Global.asax.cs file. (see below)
Any help would be appreciated and if you DOWN VOTE me, please explain why.

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.

The comments in the question solved my problem. I've posted this answer for the benefit of others, #PapaBurgundy & #Rivarolle deserve full credit for the answer.
