I'm using this template for a poster presentation. In the main result block/alertblock, the math symbols do not appear in the desired size. Any help in resolving this is much appreciated.
\documentclass{beamer}
\usepackage{beamerposter}
\usetheme{confposter}
\usepackage{lmodern}
\usepackage{exscale}
\title{.}
\author{.}
\institute{.}
\begin{document}
\begin{frame}
$$\mathcal{D}$$
\[ \sum x \]
\end{frame}
\end{document}
\mathscr{} not the same size as the other symbols:

\sum, why all the text and images etc?) In fact, all you need is\documentclass{beamer} \usepackage{beamerposter} \usetheme{confposter} \title{.} \author{.} \institute{.} \begin{document} \begin{frame} \[ \sum x \] \end{frame} \end{document}, and removingconfposteralso removes the problem. (That is why we ask for minimal examples, it makes it a lot clearer where the problem actually is.) – Torbjørn T. Mar 11 '18 at 10:43beamerthemeconfposter.sty, at least the version I have, does\RequirePackage{lmodern}, so it's likely the same problem I referred to in your previous question (now deleted?), and you can try the same fix, as mentioned in e.g. https://tex.stackexchange.com/questions/119660/\usepackage{exscale}. – Torbjørn T. Mar 11 '18 at 10:47\mathcal/\mathscr? (Now that you mention it I remember you saying something about that in your previous question, but there is no mention of them in this question, and they do not appear in the code.) – Torbjørn T.

With the one I found on the internet I cannot compile you MWE because of "no line here to end" errors. – samcarter_is_at_topanswers.xyz Mar 11 '18 at 21:38
