Shamim's Plugins

You will found this option in Front-end settings (from where you send your messages)

1. Other checks have satisfactory results?
2. So only live site is not sending emails? normal emails are being sent? eg. registration email?
3. Did you do a conflict check? Eg. deactivate all plugins and activate one of default theme (eg. tweenty*) ?

Hi Pavlo
Please follow https://www.shamimsplugins.com/docs/front-end-pm-pro/troubleshoot/email-notification-not-receiving/
If still not working please create a separate topic so that i can support you better.

Most common reason for this is if any user delete that message other user cannot reply anymore by default.

You can check Front End PM PRO > Settings > Security > Reply Deleted Message

Let me know.

Please follow https://www.shamimsplugins.com/docs/front-end-pm-pro/troubleshoot/license-keys-not-activating/

Add following code in your theme’s (child theme’s if you are using) functions.php and keep there.

add_filter( 'cron_schedules', function( $schedules ){
	$schedules['every_minute'] = array(
		'interval' => MINUTE_IN_SECONDS,
		'display'  => __('Every Minute', 'front-end-pm'),
	);
	return $schedules;
});

Then add following code in your theme’s (child theme’s if you are using) functions.php. Then refresh your website couple of times then remove following code.

add_action( 'init', function(){
	if ( wp_next_scheduled( 'fep_pop3_event' ) ) {
		wp_clear_scheduled_hook( 'fep_pop3_event' );
	}
	wp_schedule_event( time(), 'every_minute', 'fep_pop3_event' );
});

I have temporarily fixed it.
It needs more testing. After testing i will include this fix in next version of the plugin.
