Overleaf AltaCV / Sidebar not show on page 2 about altacv HOT 3 CLOSED

Look for the \end{paracol} in your .tex file, then move it to the end of your first page contents (including sidebar). Add \clearpage after \end{paracol} to start a new page if necessary.

Thanks for the help, there isn't any \end{paracol} but I did solve it by using

% Make Section go full width of the page
\newenvironment{fullwidth}{%
\begin{adjustwidth}{}{\dimexpr-\marginparwidth-\marginparsep\relax}}
{\end{adjustwidth}}

\begin{fullwidth}

\end{fullwidth}

OK, it sounds like you're using a rather old version. In general it is recommended to use the current version of altacv.cls and sample.tex; see https://github.com/liantze/AltaCV.
