Produces this error

Page not found (404)
Request Method: 	POST
Request URL:

No Publisher matches the given query.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

This looks like a problem in your code, rather than Django. Please post some details to the mailing list to get help with this.

I'll note that the error is reporting a problem about the Publisher model, which is not going to be used by AuthorForm at all. So you should start out by checking you are debugging the right problem.
