Hi,
To add packages, please check this doc How to add listing packages - HivePress Help Center. If you don’t see Packages in WP Dashboard > Listings, please make sure that the Paid Listings extension is enabled HivePress Paid Listings – WordPress plugin | WordPress.org How to install extensions - HivePress Help Center. If this issue exists, please disable third-party plugins and customizations (if there are any) and check if this issue persists. If you use a caching plugin, ensure that caching is disabled for logged-in users.
I hope this is helpful to you.
P.S. Please post in English (e.g. via Google Translate); this way, questions/answers may also be helpful for others.
