Doppialinea is the name that is assigned Cron Jobs and I are shown in the Calendar of JEvents.
A "Doppialinea" is combined with the url of cron jobs, and you can see by clicking the URL in JEvents.
Now since I put "ignore embedded categories," calendar "Doppialinea" is not shown as I create an event. In this way, I see the event created in the site but have not received it in google calendar.
I hope I explained myself correctly.
I also asked for help at the site of the cron jobs and they told me that I have to ask because they JEwents everything is working correctly.
