By default, all tickets will be accessed through a URL of the type domain.com/ticket/my-ticket-title.

If you wish to change the slug ticket to something else, let’s say help, so that your URLs look like domain.com/help/my-ticket-title, you need to add a constant in your theme’s functions.php file as follows:

define( 'WPAS_SLUG', 'my_new_slug' );

After you make this change you will need to reset the permalinks for WordPress – just go to SETTINGS->PERMALINKS and click the SAVE CHANGES button. This forces WordPress to update all items to use your new slug.
