The core issue here is that the Matrix Configuration isn't showing up. The other errors you're getting are simply a side-effect of saving an FF Matrix field without the configuration.

Create a new custom field, and check to see if you're getting any JS errors. You'll probably see something about $.fn.ffMatrix being undefined.

Most likely, either your Fieldtypes Folder URL is wrong (in FieldFrame's settings), or there's an extension conflict.
