1. Sorry, we added this feature to the demo site but haven’t updated the XML import file yet. Please add a new page and set it as the Requests page in HivePress/Settings/Requests/Display section, it’ll list all requests. You can also add it to the main menu in Appearance/Menus section.
2, 3. If you mean the My Account page, if there are no listings to show the Listings menu item doesn’t appear, it appears if there’s at least 1 submitted listing. It’s the same for requests, empty pages are not available in the account menu.
4. Once a message is sent or received (if there’s at least 1 conversation started) this menu item should appear.
5, 6. Sure, please try editing the listing or vendor attributes in Listings/Attributes and Vendors/Attributes, you can add or remove custom fields this way.
7. Yes, please try creating a new page and set it as the Vendors page (the process is the same as for the Requests page).
Hope this helps.
