I've enabled the following add on here to help me edit additional fields in appointments+ admin area
But I've just noticed the following message is displaying in my wordpress dashboard. Right at the bottom above "Thank you for creating with Wordpress". I'm fairly certain it's in relation to this php as I can see that line in the code
// For each custom field, we need to get the value via JS and push it into the data sent into the ajax post call, // so that we can get it later in 'app-appointment-inline_edit-after_save' hook.
Any idea how to fix.
