ASP.NET 4.5 Forms Authentication after hosting - asp.net

Question

I have a .NET 4.5 Forms application that works great locally. Does not require any authentication and I can use all pages. However, I am able to register user, log in and log out without any problems.
On godaddy, I can get to an HTML page I put on godaddy so everything is setup fine. But when I try to go to Default.aspx, I get a log in error even though nothing is requiring authentication locally. When I try to register a user, I get this error below.
One thing I noticed is that my application is 4.5 and this error shows 4.0 at the bottom. Now on godaddy, they just say you are using 4.0/4.5. There is no separation between them. I have talked to godaddy few times but they say they have very little technical help for custom sites like this and I have to resolve these. But if the .NET version is the problem, I will convert my projects or recreate them in 4.0.

If you run the application locally, Visual Studio uses SQL Express for development. As the result, it is working without even you notice it. Normally, the database is created inside App_Data folder.
A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections.
However, when you deploy the application (to GoDaddy), you need to explicitly provide the connection in web.config to connect to actual SQL Server.
According to the above error message, you did not provide the correct connection string in web.config.
