Cannot connect to localdb on hosting server

This is a tough one.
I created a web site using Visual Studio 2013.
There are two databases in the App_Data folder.
One is to handle memberships, the other is used by a 3rd-party scheduler app.
The web site was FTP'ed to a server.
Neither database can be connected to.

Here are the connection strings for the web.config file:

  <connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-WillowLane1-f59c4ece-32dd-40f4-9451-1620648a0486;AttachDbFilename=|DataDirectory|\aspnet-WillowLane1-f59c4ece-32dd-40f4-9451-1620648a0486.mdf;Integrated Security=True"
      providerName="System.Data.SqlClient" />
    <add name="DatabaseConnectionString" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True"
      providerName="System.Data.SqlClient" />
  </connectionStrings>

I have played around with the connectionstring trying different things according to other threats I have found on the web, but always end up with an error like this:

Server Error in '/' Application.

The system cannot find the file specified

Need some guidance here.
