I just attempted cloning a known working state of a django application from GitHub, that I also know is working on another similar IDE environment and on a local VM dev environment. When I run the django app on c9, and attempt to create an account and verify the email, I am presented with a CSRF error.
I can see that the template has passed my browser the CSRF cookie, but I’m still getting the error for reasons unknown to me. I do not have this problem with this same exact code in any of my other dev envrionments or in production(heroku).
All of my form templates have the csrf tag set correctly, and csrf middleware is enabled in django settings.
