Thank you Arturo for the effort. The problem with the “d” was in the .mo file and I changed that yesterday, thanks to other helpful people in this forum.

How did you know how to help me with the for me unknown picture in the header? How should I have thought to find it myself?

I find the structure of bbPress hard to understand. I would like to see a picture of the start page and explanations for where in which file the different elements are defined. Anyone interested in trying to create such a picture?
