Oh man…
im very sorry, that i wasted your time.
I implement an override, to change the table layout to a div based layout.
I didnt know that the same file for the form also is used in backend.
I forgot to copy
<?php
global $EM_Location;
if( $EM_Event->location_id !== 0 ){
$EM_Location = $EM_Event->get_location();
}elseif(get_option('dbem_default_location') > 0){
$EM_Location = em_get_location(get_option('dbem_default_location'));
}else{
$EM_Location = new EM_Location();
}
?>
Thank you very much for your help! Im just dumb 😀
I am using the normal submission form of the plugin, i dont know how its called.
Shortcode: [event_form]
you can try under Events > Settings > Formatting > Date/Time section > Date Format
That was exactly what i wanted, thank you!
