Post-notification plugin
To prevent users from selecting categories that the site admin doesn't want them to subscribe to:
- In 'post-notification' folder, open file 'functions.php'
- Find line #294:
$cats = get_categories(array('hide_empty' => false));
- Replace by:
$cats = get_categories(array('exclude' => 'X,Y', 'hide_empty' => false));
- Then find line #296:
$cats = get_categories();
- Replace by:
$cats = get_categories(array('exclude' => 'X,Y'));
where 'X' and 'Y' represent the ID numbers of the categories you want to exclude, separated by a comma -- check your categories' ID# at http://your_domain/your_wordpress_folder/wp-admin/categori… --; sort your excluded categories' ID# in ascending order.
