Thanks for the plugin, it's perfect for booking of our shared apartment abroad. I've configured everything and started using it, but I've noticed that all AJAX actions just hang there, and there is no response back. For instance, when I add a booking I just get the spinner, but no confirmation what so ever.
No matter how long I wait, I don't get any feedback. Same goes for actions within the WP-admin. I notice that the actions work, and they do what they're supposed to but the lack of feedback is quite annoying.
I'm guessing that this is a bug, and as a PHP developer I'd be happy to assist you in debugging if you need my help.
