Hello Maria,
Sorry for the late reply. There are 2 ways to do this. First you can actually configure this using the Menu Item List Limit/pagination. You can also go to the file
JOOMLA/components/com_easyblog/views/categories/view.html.php
and change the codes in line 79 from
$initialLimit = ( $app->getCfg('list_limit') == 0) ? 5 : $app->getCfg('list_limit');
to
$initialLimit = 100;
Hope this helps.
Thanks!
