Hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
Currently I am not able to access your site so I am not really sure which caused this but can you check your current template directory folder and see whether you have override any file for Easydiscuss in previously?
e.g. JoomlaFolder/templates/eximium/html/com_easydiscuss/tags/default.php
If yes, can you temporary rename this
default.php file and see whether that pagination got show up or not?
By right, it should show the pagination bar in the bottom, you can refer on my attached screenshot below.
If don't have any template override file, can you update your site Joomla backend and FTP access at
