I already asked this on https://github.com/deselaers/latex-beamerposter/issues but the project seems a bit deserted. Be it as it may, please consider
\documentclass[presentation]{beamer}
\usepackage[orientation=landscape,size=a4,scale=4]{beamerposter} % e.g. for DIN-A4 poster best for iPad writing
\usepackage{lmodern}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\begin{document}
\begin{frame}[label={sec:orgcfcdac7}]{This is a test of footnotes}
Consider\footnote{in the literal sense}
\end{frame}
\end{document}
when compiled it always inserts an empty page before the frame page. Does anybody have an idea how to solve this? thanks and regards
