# Major problem with biblatex/biber

I've come to work today to find that over the weekend Biblatex has thrown a wobbly and no longer works. Every time I try to run it, it goes immediately to 'process exited with error(s)', and won't display what errors these might be, preventing any troubleshooting of the problem.

I can run PDFLaTeX ok on the file, and it was all working fine on Saturday.

I can't even get this M(N-)WE to compile when including Biblatex :(

\documentclass[oneside,12pt]{article}

\usepackage[sorting=nyt,
style=authoryear,
%hyperref=true,
backref=true,
maxbibnames=99,
maxcitenames=1,
uniquelist=false,
uniquename = false,
dashed=false,
backend=biber]
{biblatex}

\begin{document}

\cite{Karlstrom2006}
\cite{Cerveny1971}

\printbibliography

\end{document}


My actual file is a great deal more complex of course, and using a custom class, but as I say, this all compiles ok in PDFLaTeX, it is Biblatex where it is falling straight over the cliff.

I've reinstalled both biblatex and biber packages, with no effect.

Has anyone else ever come across such a problem? I think this is different to other biblatex compilation problems as there is no error log output to locate the issue.

Many thanks

• I should also have said, I'm compiling using Texmaker, currently v4.0.4 but I'm updating now to see if that does anything (not very optimistic). – Mike Feb 10 '14 at 11:53
• biblatex is a package, it doesn't give messages like "process exited with error". You probably have problems with biber. Try to run biber on the command line to get better error messages. Or check if the blg-file says something. – Ulrike Fischer Feb 10 '14 at 11:57
• Thanks Ulrike, could you suggest the cmd line input? I've very limited experience running programs from there. – Mike Feb 10 '14 at 11:58
• It looks as if no .blg file is being generated - could that indicate what the problem is? – Mike Feb 10 '14 at 12:03
• Delete the folder starting with \par mentioned in your error message. – Ulrike Fischer Feb 10 '14 at 12:57
