You have 2 ways to view your vehicles.
- Enter the shortcode [cd_inventory] into a page, save it and then view the page.
- You should now be able to go to http://my_site/cars-for-sale and see a list of all your vehicles.
If your single vehicle pages produce a 404 error then go to Dashboard->Settings->Permalinks.
Add this as a custom permalink; /%postname%/%post_id%
Now click save. Cross your fingers and your single vehicle pages should now load.
