From what I can tell from other posts is that I am having a problem with my connection string to the database. However, I've copied the supplied connection string from AppHarbor and put it into my web.config.

Until now I've only ever run my app on localhost and everything has always run just fine. Can anyone please provide some advice?

Answer 1

Turns out, I did not include the new SQL server connection string for both of my applications connection strings. While most of my application uses a custom made connection string, DefaultConnection was being used for the login and Register pages.

Once I added the connection string provided for me to the DefaultConnection everything worked fine.
