Most of the bug reports from outside users are not bugs at all, simply misconfigurations. Or alternatively, do not contain nearly enough information for a developer to replicate the problem. If a bug report does not contain the appropriate information to verify a legitimate bug, it will be rejected.
The bug tracker is never to be used for support issues.
Unless you have a very specific description of the problem, including which portion(s) of the underlying system are causing problems/misconfigured and how, you should inquire about your problem using one of our available support channels. If/when a specific bug is found, a bug ticket can be opened.
An example of an invalid bug report is "XYZ doesn't work!" without appropriate accompanying detail. An alternative, to make that a legit bug report, is "XYZ doesn't work, because the underlying xyz.conf has option1=1 where it should be option1=5 when I check box A on thispage.php in the web interface".
If you have a specific, legitimate bug report, please open a ticket in our bug tracker.
For anything that is not a specific, detailed bug report, post to the forum or mailing list first.
