Hi,
i forgot to inform that i already changed website server for tests, nothing helpfull.
Fsockopen function is enabled, no DISABLE_WP_CRON in wp-config.
In WP CRON EVENTS i see:
pnfw_send_notifications_for_post_in_background [48] 2016-10-18 09:12:25 (now) Non-repeating
But nothing delivered. This still can be some hosting problem ?
I press “Run Now” – nothing happened :/
