Custom Object

Your object configuration is *almost* right. Here's the few things that don't seem quite there:
- It's unpublished - This is probably obvious, but still pointing it out.
- The query params are half correct. You have:The option part is correct. The view name likely isn't. The view=xyz should be whatever is shown in the URL (when SEF URLs are turned off). You can use anything in the URL, like a catid, Itemid, or anything else that may help specify the right 'group' of listings. For instance, if all of your listings in the Classified Listings category have a URL like:
index.php?option=com_djclassified&catid=12&view=listing&id=12
index.php?option=com_djclassified&catid=12&view=listing&id=2520
index.php?option=com_djclassified&catid=12&view=listing&id=329&Itemid=23

The following are all 'common' to the listings in that category:That's what you'd put in the Query Params box. Please note, the URLs above are completely made up, so that example will almost certainly not work for your site.

For the Open Graph Tags box, you should specify any common tags you want to use for all listings, like a generic image for vehicles (on the Vehicle Object) and another for property (on the Property object), like:
If you have a category for just Chicago, you could even add Open Graph tags to just that category's object, like:I hope that helps explain a little bit more. Once you think you have tags setup for a page, you can always check them with the Facebook URL Debug Tool:
developers.facebook.com/tools/debug

The Input URL is simply the page from your site that you want to 'test'. It can be any URL on your website. Once you enter it in the Debug Tool, Facebook will scan that page and let you know the Open Graph tags and other information it detects on your page.

I hope that helps,

For the image size warning, I wouldn't worry about that. It shouldn't prevent your actions from posting, it just means that Facebook may not use the image that's specified in the og:image tag.

As for the objects, on this page:
shbang.co.nz/index.php?option=com_djclas...d=703#dj-classifieds

The og:type is set as "company". I'm not sure where that's coming from. Some object you created is setting that, or you've used an override. From the above images, the og:type should be "Classified Listing".

Speaking of which, object types generally don't have spaces. Please click the "Get Code" link in the Facebook developer area for the object you're trying to use. Go to the Tags or HTML tab and look at what the og:type is being set there... then, use that in the Object area of JFBConnect.

I hope that helps make some more progress!

Thanks,
