I am using Bugzilla for our organization and was looking for some specific reports e.g https://bugzilla.wikimedia.org/weekl...20&days=7.

Is there any way to have the same report or some way to get the reports customized our requirements?

P.S. I am using Bugzilla 4.0.1 and getting an Error message while clicking the Old Charts option in Reports

Thanks with Regards,
