[Plugin: Events Manager] Theme the Event Page -> Booking

you could do this by editing your template files e.g. https://wp-events-plugin.com/documentation/using-template-files/

you want templates/event-single.php

I tried that but as you can see the file happen to be empty. There is only a function. The documentation as well doe not help much it just talks about an alternative way to affect the templates. I doen’t mention anything about modifying certain layouts, which template is used depending on the situation and etc. I believe that should be documented as it is a necessity for development and theme modification.

<?php
/*
 * This page displays a single event, called during the em_content() if this is an event page.
 * You can override the default display settings pages by copying this file to yourthemefolder/plugins/events-manager/templates/ and modifying it however you need.
 * You can display events however you wish, there are a few variables made available to you:
 *
 * $args - the args passed onto EM_Events::output()
 * THE LOOK CAN BE MODIFIED IN THE SETTING PAGE
 */
global $EM_Event;
/* @var $EM_Event EM_Event */
if( $EM_Event->status == 1 ){
	echo $EM_Event->output_single();
}else{
	echo get_option('dbem_no_events_message');
}
echo("sss");
?>

i’ve found another way to fix it, the page i was looking for was indeed in the template section EM ->Template ->Template -> my-bookings.php
The button I was looking for happen to be there.
