I have tried to change the way of citing multiple references from [1,2,3,4,5] to [1-5]. I have added a line \usepackage[style=numeric-comp]{biblatex}, but the references just turned from numbers to names of authors and I got a lot of warnings. Then I have deleted this new command and the document just got plenty of errors and can't be compiled. I guess that something happened to the way the references were defined before this new command.
Please help me to return my document compilation.
.aux,.bbl,.bcf, ...) and compile again with the full LaTeX, Biber, LaTeX, LaTeX cycle (where "LaTeX" stands for your favourite flavour of LaTeX: pdfLaTeX, LuaLaTeX, XeLaTeX, ...). – moewe Dec 25 '19 at 19:55\usepackage{cite}is not actually what helped per se. It just forced you to go through the normal LaTeX, Biber, LaTeX, LaTeX compilation cycle, which made sure that the output is correct. – moewe Dec 25 '19 at 19:59
