Good day, this is what happened: when logging in to the admin panel on the django site, instead of transferring to / admin (admin address) after a successful login, throws it to "/ accounts / profile /" (standard redirect after login) - t .about. we get 404 error. In other words, the url stopped forwarding after a successful login (? Next = value). The site works under Django 1.3, Python 2.7.1+, worth grappelly 2.1. There are doubts, what can this old grappelli confuse all ends? Can someone come across this?
