--This report Based on BiSR_10.2.1.zip and recently updated Wow client on 18/Nov/2023
--This is my first time to use this addon. So I might miss previous changelog about this issue, anyway i am reporting now.

--overview
There is commented(by Dioxina) lines in that file from line 393 to line 457.
And because in those lines have two definitions(reportButton, dropdownReport) which is hidden by commenterizing, this addon keep calling nil value whenever it calls reportButton and dropdownReport.
I uncommenterized those lines and reload ui, so far so good.
Tell me if I should comment those lines again or redistribute without comments please. Thanks.
