Good afternoon.
Cron worked.
The logic of the system is such that the cron must work correctly or the next one will start in 4 hours.
Cron was unable to work at 8:00.
You changed the settings later.
In logging you can see:
http://metrader.com.ua/admin/shop/report/logs/in fatal-2020-11-26.log (or yesterday)
You can see what exactly was out of memory, in this case
Export products in XML format (Rozetka.ua) = box_auto_action_price_place_rozetka
Kron does not have enough memory of 1GB to work out, you need a setting to change the limits.
We can set up 1 hour.
