Upgrade problems 6.2.5 to 6.3.2

Hi seafile community!
I’m trying to upgrade from seafile server 6.2.5 to 6.3.2 without success so far. After the upgrade seahub crashes when requesting the login page with the following exception (I’ve set DEBUG = True in seahub_settings.py to get this):

TemplateSyntaxError at /accounts/login/

‘future’ is not a registered tag library. Must be one of:

It seems to be Django and/or Python related, but this is behond my knowledge.

Did anyone faced this issue and can help?
Btw I’m using Ubuntu Server 16.04.5 LTS, Apache and MySQL and did the upgrade as described in the upgrade manual. No problems with seadrive, just seahub is broken.
Best regards

Can you please post seahub.log, seahub_django_request.log and you nginx config for seafile?

Hi bionade24! Here are my logs since the upgrade.

seahub.log:

(removed)

There are no entries in the seahub_django_request.log since the upgrade.
I use apache, not nginx. Here is the config:

Thanks for ur assistance!

Seems you changed some rights of the folders before. Execute chmod -R a+rwx seahub-data and chmod -R a+rwx seafile-server-latest and then reupdate.

Found the solution here.

It seems that the added customization support in 6.3.0 CE and previous manually customizations broke things.

Nevertheless many thanks!
