As we can check that you have raised a ticket also.
On the ticket, we found that you are using an incompatible payment gateway module.
Please note that any Prestashop payment gateway module will not work on QloApps as it should be.
We will have to make it compatible with QloApps.
Right now we do not have such a module. But it is on our road map and we will make it in the future. But right now I cannot quote a time frame.

Our Room Block shows the room types that you have created on your system.
So if you have made rooms or hall they will be shown in this blog only.
The configuration of this can be found in the Hotel Reservation System Tab--> Hotel Room Blockhttps://prnt.sc/p5y20y
Yes, this can be achieved. You can install QloApps on your sub-domain. And then you will have to contact your hosting provider to work on your URL so that user does not come to know that it is a sub-domain.
Yes this can be done. But it will have a lot of complexities. For an example, if we import an order then we will also have to import the room type, customer and taxes.
So there will be efforts involved and that is why it will be a Paid Service.
Please raise a ticket so that we can discuss it further. https://webkul.uvdesk.com/en/customer/create-ticket/
