I'm trying to use apa style with biblatex but I get "Undefined control sequence." right after \printbibliography.
Here's the code:
\usepackage[main=portuguese]{babel}
\usepackage{csquotes}
\usepackage[style=apa]{biblatex} %apagar o de baixo
\DeclareLanguageMapping{portuguese}{portuguese-apa}
If I remove the option "style=apa" it works well.
I get this warning "File 'portuguese-apa.lbx' not found!(biblatex) Ignoring mapping 'portuguese' -> 'portuguese-apa'."
I think the error origins because of not finding the file.
Found these files: https://www.ctan.org/tex-archive/macros/latex/contrib/biblatex/latex/lbx.
But I don't know where to add the file.
.lbx
, send it to me (APA style author) and I will include it with the style.
