new user registration in development

If I clone Misago & run it with ./dev init & docker-compose up, when I try to register a new user, after filling the form & pressing Register account, I get this error :

I think the problem happens when Django csrf middleware compares the 2 csrf tokens.
But the browser is actually sending 3 csrf tokens. Here are the two relevant headers :

Cookie: misagocsrftoken=TcoSGGsZxZd7VUnzELIDCk8PWmyH0HdlI104obbiyPHETszgBt5Qk5QPSD5XBPFD;csrftoken=va4PO9XeIIWiRcnWf3ptTiavJLj5bN8LKHlCAFuGvVjSGr8innGo82g0ULXzv7mo; djdt=hide; sessionid=7kq2qap6wg05ddwq0zibh8eic1xg7my7
...
X-CSRFToken: TcoSGGsZxZd7VUnzELIDCk8PWmyH0HdlI104obbiyPHETszgBt5Qk5QPSD5XBPFD

That doesn't happen when I install misago_docker in a Digitalocean droplet.

Am I doing something wrong ?

Oh !. That make sense. I was previously playing with misago_docker in my local development & it's cookies where still in the browser. Well, I learned something today.

BTW, I submitted a pull request. There's probably something wrong, so feel free to make any recommendations or changes needed. thanks.
