While compiling to pdf a LyX document that uses packages frenchle and endnotes, I get: "You are using two French options for Babel" when I try to generate the pdf.
The solution is given here for German:
% JK Introduced \notesname in the spirit of international \LaTeX.
% JK \notesname is set per default to be {Notes}, but can easily
% JK be redifined, e.g. for german language
% JK \renewcommand{\notesname}{Anmerkungen}
But after several tries, I realy don't know how to apply it. "Anmerkungen" means "notes" in english and "notes" in french, so I imagine I should not need it anyway.
If I add \renewcommand{\notesname}{Notes} in the preambul, it changes nothing.
If I add it in the document in a TeX box before the one for \theendnotes, or in the same box, it changes nothing.
Here is a MWE:
