Hello.

My client buyed Amelia booking plugin, but unfortunately plugin does not work in frontend of my custom theme. It perfectly works in admin and also seems plugin perfectly works in frontend in default wordpress themes like twentynineteen or so. However I need get it work in custom theme. Perhaps it should be something in functions.php or so? It displays nothing and just generates next code (seen after pressing CTRL+U):

<div class="wp-block-amelia-booking-gutenberg-block">
<script>
  var hasBookingShortcode = (typeof hasBookingShortcode === 'undefined') ? false : true
  var bookingEntitiesIds = (typeof bookingEntitiesIds === 'undefined') ? [] : bookingEntitiesIds
  bookingEntitiesIds.push(
    {
      'counter': '0',
      'category': '',
      'service': '',
      'employee': '',
      'location': ''
    }
  )
</script>
<div id="amelia-app-booking0" class="amelia-booking amelia-frontend amelia-app-booking">
  <booking id="amelia-step-booking0"></booking>
</div>
</div>
<div class="wp-block-amelia-catalog-gutenberg-block">
<script>
  var bookingEntitiesIds = (typeof bookingEntitiesIds === 'undefined') ? [] : bookingEntitiesIds
  bookingEntitiesIds.push(
    {
      'counter': '1',
      'employee': '',
      'location': ''
    }
  )
</script>
<div id="amelia-app-booking1" class="amelia-service amelia-frontend amelia-app-booking">
  <catalog></catalog>
</div>
</div>

Thank you for helping!
