Burp suite version is V2.1.03

Fristly i clicked ‘Launch sumllge probe’, and waited for the probe completed, but i can not find 'Smuggle attack' button in menu on request.

I had the same experience and found that Smuggle Attack options only show up if you are using a request that already has both headers in it (you can paste them in): Transfer-Encoding: chunked Content-Length: 25 (or whatever number...)
