Unable to restore whatsapp chats

i recently flashed my REDMI 4 Device with MOKEE 7.1.2 ROM . Everything is working fine. But i am unable to restore my whatsapp chats. Every time i click on Restore backup, upon 24% it shows this error: "Unable to restore your chats from this backup. Do you want to restore from an older backup? "
I tried to restore my whatsapp backup on MEMU Emulator and it worked.
So how to restore my chats on this rom. I know this rom is causing issue.
