Hello, on your side you advertise the complete German language pack.
I have installed the German language version 188.8.131.52 and found that in the administration under Global settings 13 missing translations are included.
The DJ-Classifieds German language pack is 100% complete and it's available to download. It's compatible with the latest component version. You were right, the latest package was not working correctly. Meanwhile we had to make some changes with translations that's why it took a long time.
