Hello Emmanuel

How many appointments do you have during the day? How many employees, services and categories do you have?

I can see that you made some modifications to the form (which looks great, by the way!), so that could also be affecting it. What's your hosting plan, are you maybe on a shared hosting? The form loads within a couple of seconds if you don't have hundreds of appointments during the day, or if you don't have a hundred employees, so other than a low hosting plan, nothing more comes to mind.

One more thing, actually - try disabling caching for the booking page - see if that helps.

Hello Emmanuel

1. I don't know - are you saying it used to work fine?

2. This could be a problem. Amelia sends 2 - 3 admin-ajax calls when the booking form loads, so if your hosting plan is low, it can cause issues.

3. and 4. That's just fine, it should be working normally.

This issue is most likely linked to the shared hosting. You have a nice website, with great visualizations, which unfortunately takes a toll on the server load. For websites that look as well as your website does, it's always recommended to opt for dedicated hosting. Your content grows, your cache grows, everything will eventually lead to the site being slower with the amount of data you have, and with the number of traffic increasing.

I just checked the booking page from my mobile device, and it loaded in around 15 seconds, so significantly better than on Friday. Did you make any alterations?
