I use the following lines of codes to use biblatex. It all works, but the following: At every citation the citation looks like: [ 1] instead of [1]. This is true for all citations in the document. And I'm out of ideas how to solve this. Any help is appreciated. Thanks a lot in advance.


%  \setunit*{\adddot}% DELETED
  \setunit*{\addnbspace}% NEW (optional); there's also \addnbthinspace

  • Welcome to TeX.SX! % at the end of \AtEveryBibem lines is not so important, because the items are evaluated when TeX is still not typesetting the entry; conversely, they will produce a space when the code in \AtEveryCitekey is performed.
