I open the Execute Anonymous Window and Execute the following test line:
And nothing appears on the Log tab.
It now works. I do not know exactly what it made it work.
But this is what I did:
Deleted trace flags
Moved Expiration to an arbitrary value of 4:00 PM
Closed the console
Opened the console
Expiration went back to “12:NaN PM” (still highlighted)
Weird, but it works.
