polyglossia loaded after biblatex

[Wolfgang Engelmann]

Hi,
i get an error
! Package biblatex Error: 'polyglossia' loaded after biblatex.

However, in the tex file it comes BEFORE the biblatex

\usepackage{color}
\definecolor{fg}{rgb}{0.000000,0.000000,0.000000}
\definecolor{bg}{rgb}{0.980392,0.941176,0.901961}
\pagecolor{bg}
\usepackage{polyglossia}
\setdefaultlanguage[variant=british]{english}
\usepackage[style=biblatex-spbasic]{biblatex}
\def\lyxlock{}

I am not sure were in the LyX file polyglossia is set;
should be another name.

I use Komascript book style, Debian, Lyx 2.4.0 dev

Question: Were in the lyx file can I correct the error?
