hey there,
i had the same problem.
this is what i did to fix it:
>>> go to the post-per-cat plugin folder
>>> inc > widget.php
>>> search for:
‘posts’ => (empty($instance[‘posts’]))?5:$instance[‘posts’],
>>> and for:
$posts = ( isset( $instance[ ‘posts’ ] ) ) ? $instance[ ‘posts’ ] : “5”;
>>> change the number of posts to whatever you want
>>> upload your new widget.php
on my wesite it’s working.
remember to make a backup before trying!!
good luck 🙂
