当我的投影机的幻灯片数量超过 10 张时，幻灯片右下角的日期无法正确显示。

我该如何修复它？

Answer 1

尝试对脚线进行以下重新定义：

\documentclass{beamer}
\mode<presentation>
{
  \usetheme{Madrid}       
%  \usecolortheme{default} as the name says, this is default
  \usefonttheme{serif}    
  \setbeamertemplate{navigation symbols}{}
  \setbeamertemplate{caption}[numbered]
} 
\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel}
\usepackage{chemfig}
\usepackage[version=3]{mhchem}
\usepackage{caption}
%\usepackage{epstopdf} not needed with current tex distributions
\usepackage{comment}
%\usepackage{graphicx} not needed with beamer
\usepackage{subfig}

%\definecolor{ao(english)}{rgb}{0.0, 0.5, 0.0} Better not use () in colour names 

\usepackage{pgfpages}
\pgfpagesuselayout{resize to}[physical paper width=8in, physical paper height=6in]

\makeatletter
\setbeamertemplate{footline}{%
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
    \usebeamerfont{author in head/foot}\insertshortauthor\expandafter\ifblank\expandafter{\beamer@shortinstitute}{}{~~(\insertshortinstitute)}
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
    \usebeamerfont{title in head/foot}\insertshorttitle
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
    \usebeamerfont{date in head/foot}\insertshortdate{}\hfill%
    \usebeamercolor[fg]{page number in head/foot}\usebeamerfont{page number in head/foot}\makebox[0.9cm][r]{\usebeamertemplate{page number in head/foot}}\hspace*{2ex} 
  \end{beamercolorbox}}%
  \vskip0pt%
}
\makeatother

\title[Unal]{}
