I am trying to use [biblatex-mla](http://www.ctan.org/pkg/biblatex-mla) to create a bibliography and cite works from it. Here is an example text with some citations:

```
\documentclass{article}

\usepackage[utf8]{inputenc}
\usepackage[british]{babel}
\usepackage[babel]{csquotes}

\usepackage{filecontents}
\begin{filecontents*}{references.bib}
    @book{saussure,
        author    = "Ferdinand de Saussure",
        title     = "Course in General Linguistics",
        year      = "1966",
        publisher = "McGraw-Hill",
        editor    = "Charles Bally and Albert Sechehaye and Albert Riedlinger",
        address   = "New York",
        edition   = "3"
    }
\end{filecontents*}

\usepackage[backend=bibtex,style=mla]{biblatex}
\addbibresource{references.bib}

\begin{document}

While the horizontal axis (AB) depicts the coexistence of several entities at a specific
moment in time, the vertical axis (CD) additionally represents the changes of these
entities over time \autocite[80]{saussure}. By virtue of the complexity of the system of
language, it seems obligatory for the linguist to draw a distinction between the two axes
\autocite[81]{saussure}.

\printbibliography

\end{document}

```

The problem is that the space between the author name and the page number is missing. I have tried to illustrate this in the following picture.

I am (and must be) running on [ShareLaTeX](http://sharelatex.com) – hence the `backend=bibtex` option to the `biblatex` package, as suggested by [their BibLaTeX example](https://www.sharelatex.com/templates/bibliographies/biblatex/). I have tried to use Biber as a backend on my local machine instead, though, and got the same faulty results.

Does anyone know how to fix this?
