Login not allowed from /accounts/login/

Log-in is not allowed from the following URL: `https://identities.biterg.io/accounts/login/` .

The log-in form appears but when you enter the credentials and then submit the form, it returns the following error:
```
Not Found
The requested URL /accounts/profile/ was not found on this server.
```

Reproduce the login flow at /accounts/login/ and inspect what happens when the form redirects to /accounts/profile/. Trace the missing destination and verify that submitting valid credentials reaches an available profile page without returning Not Found.
