Error after publishing site: The type specified in the TypeName property of ObjectDataSource 'PositionPostingsDataSource' could not be found.

I have a asp.net v2 website that runs fine on our development server. I have
published the website to a stage server and it runs fine, but when I publish
it to production I get the following error:
The type specified in the TypeName property of ObjectDataSource
'PositionPostingsDataSource' could not be found.

The dll that contains the type that can't be found, is the same version as
the dll on the development server and on the stage server.

Has anyone got any hints to what could cause this error.
