When naming your po
and mo
files in a theme, you need to only make use of the language code to name these files. Any other convention will not work
For example, my blog is in Afrikaans and the localization language code is af_AF
. My mo
and po
files are named accordingly, ie, af_AF.po
and af_AF.mo
I’m not sure what the codes are for German, but change the filenames accordingly
