avijit well i know your frustration
sites that i manage on reshare.pm they had alot ddos lately
i just giveup using aapanel and now moving on pure golang
maybe my suggestion is make new system from it instead asking third party to patch it which is will never happen....
as i said aapanel is very least things you can hope outside what they already given.... if bug maybe they will fix it but if feature, you should suggest it to bt.cn first and if it's approved they will appear on aapanel 2-3year ahead
but if not
well...
there's no hope for it
