Moving ASP.NET MVC website to a server

Ive been developing a website in VS 2013, and been testing it using the built in IIS.

Ive not decided to move it to the server where it will eventually lie.

I have all my dll files in the bin folder, published the project etc, but i still receive

Internal Error 500

I previously had to downgrade my project from .NET 4.5 to 4.0 because there is no option to upgrade my server. Therefore i had to change alot of the web.config files

Any ideas why i still receive this error?
