Thank you for the prompt reply. Have the translation gladly made as a small contribution by me. Would like to deliver the package installable via the package manager. Question about this: Do the files have to be written in "/TinyPortal/Views/languages/german-formal"? Or is the default path of ElkArte fine, too?
I also noticed two errors already. However, with one of them I don't know if it is possibly due to the server. Link to the test installation in the signature.
First (TP credit link):
Exception: Call to undefined function TinyPortal\Controller\tp_hidebars()
Second (link to the list of "articles in category" below an article):
Warning: Undefined array key "email_address"
Life usually gets hectic when you have plans. Unfortunately, mostly also in the opposite direction.
