Status System Logs Settings Remote Logging Options - No toggle all
Go to Status => System Logs
Click Enable Remote Logging
There is a radio button down the end "No toggle all".
In status_logs_settings.php that is created with a comment:
Ugly hack to prevent the "Toggle all" button from being automatically created
And there seems to be code that attempts to hide it, but it is visible for me.
What is that all about?
