Hi, yes, the docs tell the difference between different options, but, they don't tell, for example, that notifications won't work using ajax cron option.

Where does this statement is written?
Maybe no one visits your ownCloud web page and not cron is triggered?

Or is there an explicit notifications.php that I have to add to the cron file?

No. Cheers
