Hi, When I try to migrate an existing table, I get the signature version is not supported error.

What to do?

Thank you!

@thismatters I am having the same issue and I am usng 0.3 and Django 1.11?

Any updates on this, my entire app is down because of this bug.

I had this same error. It can be rectified by deleting all of the previously saved records of your model. This solves the BadSignature error, but another Field Error pops up, which I am unable to rectify.

Please see the advice in #44 before acquiescing to any data loss! Often this issue crops up because of a change to a dependency deep in the cryptography stack and can be fixed by re-assessing/updating those dependencies.
