Django CMS pages not visible after server restart - django-cms

Question

I've been using django-cms to build a simple website for my GF. I was editing the base template and for some reason my changes were not going through, so I restarted the nginx server script only to find out to my horror, that I can't see any of the page content anymore, only their names in the tree in the admin interface. If I try to go to a page, it claims the page does not exist.
I thought maybe there is something wrong with the setup so I ran fix-tree and migrate (which might have been an error on my part) and now even the page names are not visible anymore in the admin interface. The pages and their contents are in the database, but they are not accessible anymore.
Has anyone run into a similar issue? What could be a possible cause / solution for this? Any ideas where to look
My guess is that something was wrong with the setup or perhaps I had a wrong version of some package and then I didn't run into trouble until I restarted.
I would love to have all those pages back especially that they still exist in the DB. Will be eternally grateful for any help.
EDIT
I just tried creating a new page. I was able to do this without any errors, the page is visible in the database but it is not visible in on the "Pages" page and the page slug gives an 404 error.

#Paulo Thanks for asking for these. Now that I looked at the requirements and settings file, I see that the requirements file I had on my local Pycharm dir had not synced with the one on the server. At some point I must've accidentally upgraded to Django 1.9 in the venv of the server. Now I guess that when I restarted that's when the Django-CMS picked up the change and lost the page contents. Then when I saw the loss and downgraded back to 1.8, that's when I lost the page names as well on the pages tree. I'll start by going through the changes between the two and also see if the packages are up to date with what they should be.

Answer 1

OK I managed to fix. After stepping through the code in the debugger in Pycharm, I realized I accidentally commented out the
LANGUAGE_CODE = 'en'
line in settings with made Django revert back to LANGUAGE_CODE = 'en-us', and that why it couldn't find the pages.
I also had a syncing problem between PyCharm and the deployment server, which is why the LANGUAGE_CODE = 'en' was not commented out in the settings.py I posted here.
So in short:
TIL that the language code must match in both
LANGUAGE_CODE = 'en'
and
CMS_LANGUAGES = {
1: [
{
'name': gettext('en'),
'redirect_on_fallback': True,
'code': 'en',
'public': True,
'hide_untranslated': False,
},
],
'default': {
'redirect_on_fallback': True,
'hide_untranslated': False,
'public': True,
},
}
