So then the problem is in most probably in your init file.

That’s a bad idea. You are lying to tmux that its underlying terminal
is screen-like, while it is in fact xterm-like. Additionally, other
programs, if you run them outside tmux, will misbehave.

Normally, tmux sets the TERM variable for processes running within its
session. It uses "screen" by default, but you can control it with this
line in your .tmux.conf:

   set -g default-terminal "screen-256color"

These are the decoding sequences for Page Up and Page Down. When you
start Emacs with your customizations, you can look for these. If they
are not there, find what deletes them.

Also, see if you are binding M-[ or ESC [ to anything. If you do, many
function keys, including Page Up and Page Down, will probably stop
working.
