In answer to your questions:
- Currently we could not confirm that Vantage works with WPML out of the box,
this post explains a little more about our themes and that plugin in particular.
- We're not aware of anyone who has advised that they are using this with our themes which could clarify if it works.
- AppThemes doesn't officially support third party plugins, so we unfortunately cannot confirm that such plugins are definitely compatible with our themes.
- Whilst the demo site is fully functional, you cannot save data to it which is why you cannot complete the listing process (there should have been a pop up to explain this upon entering the demo). In terms of free trial listings though, no payment information is required
- There are no other options in the Vantage admin dashboard aside from sidebar widgets, so changing the layout would ultimately involve customization on your part. Our themes are not encrypted, so you are free to make modifications if you wish.
- Listings and events are separate custom post types, so categories are set up separately.
- The Google map is built into the listing form by default, so it would require customization if you wanted to move this. You can of course give the listing a general location rather than a specific address also. Thanks.
