The plugin defines slug (permalinks) for different archive pages such as cuisines, courses, cooking methods, etc.
If you want to change the permalinks, navigate to WP Delicious > Settings > General Settings > Permalinks.
To change the permalinks, simply replace the default slug with your desired text.
If you want to use two or more than two words for permalinks, put – (hyphen) between the words. Don’t add space between the words.
