I read the documentation testlink on bugzilla, I modify the following files bugzilla.cfg, config.inc telque custom_config.inc like define in the documentation .
When I click the icon bugzilla for the execution of test cases, the page or adding the id of the bug in bugzilla appears, i introduce a number of bug and I am told it valid bug added.
I close the windows, the build appear.
I click to the number of bug it just opens the window bugzilla, and if I search this number there is no bug in bugzilla.
Please excuses my English,
