BibTeX, biblatex and biber ⇒ Error with \printbibliography

[Asma_F]

Hi,

I used bibtex and everything was ok. I added a reference in bib file then I compiled the tex file, the following error appeared.

! Undefined control sequence.<argument> \prd \printbibliography[heading=bibintoc]

I deleted the reference and compiled again but nothing changed. I don't know what happened and what caused this error.


Thanks

You have to clear the auxiliary files as well, most importantly you bbl file.

Do you mean that I need to delete all the files dvi, blg, aux......etc?

I delete bbl file and now it works. Thank you very much
