Error registering at postgresql.org

I'm trying to register at postgresql.org so I can edit the wiki to fix a
broken link. I received a link on my e-mail so I could set my password,
but when I submit the "Change password" form I get an error:

Forbidden (403)
CSRF verification failed. Request aborted.
More information is available with DEBUG=True.

I've tried appending "?DEBUG=True" to the URL but got no further
information.

Can someone help?

Thanks,
Daniel Serodio
