Trac 1.4, User login failing

[Mo]

Hello everybody,


we have a user that cannot login anymore. I can't reproduce the issue with my own login. We have reset the password of the user, but the issue remains.
Login is failing like this:

2020-08-17 09:28:26,327 Trac[main] ERROR: [10.190.226.172] Internal Server Error: <RequestWithSession "POST '/login'">, referrer 'http://trac/pp/login'

    return string % kwargs

What can we do?

Best regards.

Hi ,

Look at the error, unspotted character. He might has a pw that can't be read, so he might like to try one without some strange special chars like ( . All those bad choices anyway since they are part of the programming language syntax and might need to be escaped.

Cheers 

Markus

The issue occurs in this block of code, which has a syntax error:

                     if release_time is not None:
                        data['login_error'] = \
                            _("Account locked, please try again after "
                              "%(release_time)s", release_time=release_time)

You can probably solve the issue by unlocking the user's account.

The syntax error is fixed in:
