How do you enable HTTP logging?

[voidpointer]

I'm trying to debug some reverse proxy behavior and I need to see the server-side logs for Transmission to understand why I'm seeing certain client behavior (specifically related to how the Transmission server is processing the Authorization HTTP header). How do I enable HTTP logging in Transmission?

Enable HTTP access logging.

Click the Lock&Edit button.

Select the HTTP access log file enabled check box to turn on the access.log.

Modify the Log file name field if desired.

Click Save andActivate Changes.

Your instructions make no sense. I do not see a lock & edit button on Transmission UI.
