Hi Nikola, I have to say that EA is by far the best appointment plugin out there. However, I have a couple of issues that I hope you can help. In my initial post, I mentioned that booking an appointment takes two time slots. So, I uninstalled EA  and reinstalled. After installation, I get the error "You can't select this time slot!' no matter what I do. Can you help please? Thank you Note: I don't really know how to edit or reply to a posted question. Therefore, I started a new thread!
