Hi dear users who use english as their default language in the forum,
we found out about a problem in the software, that might disable all german topics from your view. We are working on a better solution, but until then please do the following steps:
Go to your profile settings (click on your avatar and name on the left top corner) and go to general. Here you should select German and English at "multilingualism". this will allow you to see all german content too-- which is pretty much everything in this forum, because we never made any difference until now and German is the main language by default.
if you have any questions, please don't hesitate to ask
