Not loading and Multiple Customers

Hi there,

Recently, the booking page is not loading. The page just kept loading and I have no idea how to fix it. I made sure that there are assigned service and is using the correct Amelia bracket. Moreover, the service page only showed the word”category” instead of all classes where it usually shows.

Another question:
I set the maximum capacity for each session to be 1 person. However, I realize that there are multiple emails (customers) registered to one timeslot, is there a way to fix it?

Thank you.
