Displays the events

just to confirm, is this using EM dev versions 5.7.3.3 ?

yes,
5.7.3.3

It’s possible this is a conflict caused by your theme or another plugin. To check if it is, can you test with all other plugins deactivated and while running the default WordPress theme?

Hi,
We have disabled all plugins and have the same result. I put again version 5.6.3.1 and it works.

Just a hint…
Check the two file versions (5.6.3.1 vs 5.7.3.3) in events-manager/classes/em-calendar.php

Might be a line missing? I had the same problem with [events_list grouped], remember @caimon_nwl? ??

Okay, checked both files using Kaleidoscope:

Version 5.6.3.1, line 298-310 contains:

	if( $eventful_days_count[$day_key] > 1 || !get_option('dbem_calendar_direct_links')  ){
if( get_option("dbem_events_page") > 0 ){
$event_page_link = get_permalink(get_option("dbem_events_page")); //PAGE URI OF EM
}else{
if( $wp_rewrite->using_permalinks() ){
$event_page_link = trailingslashit(home_url()).EM_POST_TYPE_EVENT_SLUG.'/'; //don't use EM_URI here, since ajax calls this before EM_URI is defined.
}else{
 //not needed atm anyway, but we use esc_url later on, in case you're wondering ;) 
$event_page_link = add_query_arg(array('post_type'=>EM_POST_TYPE_EVENT), home_url()); //don't use EM_URI here, since ajax calls this before EM_URI is defined.
}
}
if( $wp_rewrite->using_permalinks() && !defined('EM_DISABLE_PERMALINKS') ){
$calendar_array['cells'][$day_key]['link'] = trailingslashit($event_page_link).$day_key."/";

In version 5.7.3.3 that should be on line 316, but this code is missing.
It does seem that this part is all about link to the calendar day (see old line 296 and new version line 314).

Hi,
I did update to 5.7.3.3 and after that I replaced em-canendar.php from 5.6.3.1 and it works

@romanian_pac How are you displaying your calendar (shortcode, etc.)?

I am having the same issue.

The Same way that I replaced the backup file I from the host before the update, the issue was solved.
