Hi Chris,

thank you for reaching out to us

It needs to have the ID of the button that is calling the popup, so this is how one of the shortcodes should look like in the Elementor pop-up:

[ameliabooking trigger=amelia-button-id]

so if the button ID is 1 it will be:

[ameliabooking trigger=1]

So, you create a PopUp and set this shortcode in the popup, you will see the option Load booking form manually when you create Amelia shortcode, where you need to provide the button's ID, please look at the attachment.

When you create a button, on which the PopUp will be called, you set its Button ID (that you will provide in the shortcode above afterwards):

You need to enable the "Prevent Closing on Overlay" option in the popup settings:

If this set up still does not work for you, please provide me a temporary WP-admin (administrator) user for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. 

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course, we do not provide login data to third parties. 

You can write credentials here just check PRIVATE Reply so nobody can see them except us.
