Discussion of the Web Interface for Transmission, formerly known as Clutch. This applies to all version of Transmission
To all of you still getting the eerror 403 in transmission web, DO NOT install the program and the daemon. Install one or another but not both. I spend 2h changing ports until i realize that changing the program ports don't change the daemon's and viceversa. Once i change the daemon port to another different than the program the problem was solved. Then i remove the daemon with the installer and all working again.
