Hi,
I see. Regarding redirecting to the payment page:
- Please navigate to WP Dashboard > WooCommerce > Status > Tools > and click Create pages opposite Create default WooCommerce pages.
- Please edit this listing (either on the front-end or back-end) and re-save it, setting the Price. This should generate a hidden product for a listing (or package\request), and the checkout redirect should be okay.
- Please refresh permalinks; you can check this doc: How to refresh WordPress permalinks - HivePress Help Center
- Also, please make sure you set up payments correctly; you can check this doc How to start accepting payments - 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.
Also, please check this sample topic: The booking payment confirmation page only works for some listings - #11
I hope it helps.
