I found many solutions to similar problems here, but I still cannot solve this one: I'm using Springer's template like this:
\documentclass[twocolumn, natbib]{svjour3}
\usepackage{graphicx}
\usepackage{natbib}
...
\bibliographystyle{spbasic} % basic style, author-year citations
\bibliography{my_bibliography}
and I get an error: Bibliography not compatible with author-year citations.
I really cannot figure out what I'm doing wrong.
