Internal Server Error after activating modoboa-imap-migration

[Goosse]

I seem to be having the same problem as mentioned in the link below. I have set debug to True, but am seeing no new error messages in the browser.

Ok, so I found the logs at /var/log/uwsgi/app/modoboa_instance.log.

Here is the log I am getting:

Traceback (most recent call last): File "./instance/wsgi.py", line 16, in application = get_wsgi_application() File "/srv/modoboa/env/local/lib/python2.7/site-packages/django/core/wsgi.py", line 13, in get_wsgi_application django.setup(set_prefix=False) File "/srv/modoboa/env/local/lib/python2.7/site-packages/django/init.py", line 27, in setup apps.populate(settings.INSTALLED_APPS) File "/srv/modoboa/env/local/lib/python2.7/site-packages/django/apps/registry.py", line 78, in populate raise RuntimeError("populate() isn't reentrant") RuntimeError: populate() isn't reentrant Thu Oct 5 18:24:20 2017 - unable to load app 0 (mountpoint='mail.email.wheatstatewooddesign.com|') (callable not found or import error) Thu Oct 5 18:24:20 2017 - --- no python application found, check your startup logs for errors --- mail.email.wheatstatewooddesign.com [pid: 10576|app: -1|req: -1/6] 162.201.236.210 () {48 vars in 928 bytes} [Thu Oct 5 18:24:20 2017] GET /accounts/login/?next=/dashboard/ => generated 21 bytes in 2 msecs (HTTP/1.1 500) 2 headers in 83 bytes (0 switches on core 0)

When I call service uwsgi restart as the

no python application found, check your startup logs for errors

above suggests should be done, the following is logged to that file:

So, obviously the modoboa_imap_migration is not being found...

@Goosse If you use a virtualenv, please make sure you installed the imap migration plugin into it.

[Goosse]

Does the installer use a virtualenv by default?

[tonioo]

yes it does

[Goosse]

What would be the virtualenv_path then?

[tonioo]

Default location is /srv/modoboa/env. Before installing/updating a plugin, run this:

> su - modoboa
> bash
> source env/bin/activate

[Goosse]

Thanks for your help
