Bib(la)tex error when compiling beamerposter template

Question

Dears

I have downloaded this template http://www.latextemplates.com/template/jacobs-landscape-poster but when compiling it, the texmaker gives me the following error:

Process started

INFO - This is Biber 2.5 INFO - Logfile is 'main.blg'

ERROR - Cannot find control file 'main.bcf'! - did you pass the "backend=biber" option to BibLaTeX? INFO - ERRORS: 1

Process exited with error(s)

Now I have recently updated my texmaker preferences to use biber instead of bibtex (based on suggestions I read here) by entering "/usr/texbin/biber" %

How to overcome this error? the bibliography in the template is mentioned as follows

\nocite{*} % Insert publications even if they are not cited in the poster
\small{\bibliographystyle{unsrt}
\bibliography{sample}\vspace{0.75in}}

Thank You

Answer 1

Thanks to the comments, the issue is I need to either stick with bibtex or alter the template accordingly to make it working with biblatex. I chose the later and based on the answers in What to do to switch to biblatex? I succeeded in doing so.

Simply, remove

\nocite{*} % Insert publications even if they are not cited in the poster
\small{\bibliographystyle{unsrt}
\bibliography{sample}\vspace{0.75in}}

and add

\usepackage{biblatex}
\addbibresource{sample.bib}

to your preamble and \printbibliography to the reference block

\begin{block}{References}
\printbibliography
\end{block}
