Hi,

    I am facing a new problem now. It was working fine few days ago but not now. Below are the error details,

I found a suggestion at this link https://groups.google.com/forum/#!topic/trac-users/sf1bKgcrzr4 but in my trac.ini configuration file, I have the following enabled already.

[account-manager]
password_file = /usr/share/trac/trac.htpasswd
password_store = HtPasswdStore

[components]
acct_mgr.htfile.htdigeststore = enabled
acct_mgr.htfile.htpasswdstore = enabled

Now login doesn't work and I am not able to access the site. Please help me to fix this up!

You might just try:

[components]

acct_mgr.* = enabled

if that works, you can start disabling components.

Also, check that components are loading:

I'm not sure what to make of this traceback:

File "build/bdist.linux-x86_64/egg/usr_mgr/web_ui.py", line 196, in _remote_user
    if Usermanage(self.env).check_password(user, password):

What is "usr_mgr", and "Usermanage" class? That's not part of AccountManager. And why is that path relative rather than absolute? It seems maybe you are loading an egg unintentionally. Maybe some fork of UserManagerPlugin?

Of course it is Usermanager plugin that we used in our application. I try out your suggestions. Thank you!
