Childtheme does not load parents translations

Hi Kriesi-Team,

i already posted here: https://kriesi.at/support/topic/translation-missing-child-theme/
But dondela wants his/hers own tread, so i gone away.

I’m using a childtheme to modify some css and add some functions for better implement some plugins.
Up to now i never had to do something to have german as Theme/Childthemelanguage by default.

wp-config is correct
I’m using the German WordPress Version

I don’t want to translate or change something. I want, that the german translation file of parent enfold loads correctly.

I Updated an other Site, now it’s the same there. Already got Backup.
…

i did as Andy wrote, but its the same.
I deactivated all Plugins, same.
You are allowed to change everything to get clear what the problem is.
No matter if something brakes, i have backups.

In my other Enfold installations its the same, so please write how to fix it if you got it, so i can do with the others.

BTW: the Auto Update functionality of the theme doesn’t work too (in all six installations). I already followed the instructions in the forum for that (but on first install i already installed by using ssh. It doesn’t make sense to me that this would change anything). Probably you can give me a tip on that. (Of course the file permissions are set correct.)

…
I am my own hoster. Using Veste CP on Ubuntu 14.04. I already disabled NGINX Caching and mod_Pagespeed, trying befor i contacted you.
You are allowed to test on the Site, it’s not Public yet.

If you need i can you give access to Apache Logs etc.

I think now is all information together.

Please help, even if Andy can’t reproduce, propably someone else can. I have 6 licenses and up to now i had not much to ask here.
Best Jan
