I can't figure out or find an answer on how to enable the description in the custom taxonomy category pages. Under description field it says: "The description is not prominent by default; however, some themes may show it.".
I've managed to enable it to normal category pages by adding this code to archive.php
<?php echo category_description(); ?>
But it's still disabled on taxonomy pages.
Any help will be appreciated.
I find out that my theme has taxonomy.php where this code
<?php echo term_description(); ?>
needs to be added to make the description visible on custom taxonomy page.
Thanks to @PieterGoosen for helping me out.
