Having same problem, In my case uwsgi didn't restart.
To solve the problem, I have run systemctl restart uwsgi.service

[NeitsabTeguom]

Same problem, Internal Server Error (500)
And the fix [adrians75] say, effectively not working.
Some solutions ?

Back to previous 2.1.0 temporarily : sudo ./run.py --version=2.1.0 mydomain.com

Next time i make a snapshot of the server before any updates!

[Spitfireap]

Hi @NeitsabTeguom,
It seems you are trying to perform an upgrade. Could you please check that you applied the specific upgrade instructions after your upgrade ?

As for @adrians75 and @redalert99 if it is indeed a fresh install : can you go to the modoboa-installer directory, type this command : git rev-parse HEAD and post the result ? Also can you go to /srv/modoboa/instance/instance/settings.py, set DEBUG to True then restart uwsgi (systemctl restart uwsgi) and reload the page ?

[NeitsabTeguom]

I do it but not work

[NeitsabTeguom]

Having same problem here :

SECURITY WARNING: don't run with debug turned on in production!

DEBUG = True

ALLOWED_HOSTS = [
'mail.domainwashere.com',
]
CSRF_TRUSTED_ORIGINS = ['https://*.domainwashere']

what logs file should be checked?

If you are hitting this problem and you are doing an upgrade, you need to make certain you haven't missed any of the Upgrade Specific Instructions between your old version and the new.

Pay special attention to removing old extensions that have been moved into core. I had to remove modoboa_pdf_credentials and modoboa_stats from MODOBOA_APPS, because these are both replaced with new core versions. Once I did both of them the 500 errors went away.

You will have a much easier time finding the error if you enable debug mode (but do NOT leave it on in production):

cd /srv/modoboa/instance
cp settings.py settings.bak.py
sed -i -e 's/DEBUG = False/DEBUG = True/' settings.py
systemctl restart uwsgi

Then if you trigger the error you should get some clues about what is wrong, or at least which extension is responsible.
The old extensions are not compatible with the rest of the newer code, which causes the 500 errors.

Don't forget to turn off debug mode afterwards!

cd /srv/modoboa/instance
sed -i -e 's/DEBUG = True/DEBUG = False/' settings.py
systemctl restart uwsgi
