Error on Django Form Wizard - Resets to wizard to step 0 with no data on submit

I'm using the django form wizard and its sporadically will reset the wizard to step 0 after submitting the form on the last step.

This only happens very occasionally, and there doesnt appear to be any pattern to indicate why this happens.

Can anyone sugg开发者_如何学Cest a possible cause or way to investigate this? Frankly i'm not sure where to start to investigate this.

thanks

check if you have any global variable that someone else, on another browser, is resetting
