We have two sites which both have the cb subs installed, one is test site, one is live site, the sbsubs url integration worked well in the test site, but had problem in the live site, the setting between the test site and live site are same, and also the two site are deployed in a same server, so they have the same execution enviroment. I double checked just now, for the live site, sounds like didn't send the request. I can't debug this issue, since all the code is encoded, can you tell me is there any way I can debug with the cb subs.
