Progmem will not compile on wifi1010

Official Hardware MKR Family MKR WiFi 1010

Please can somone help
This code will compile for a Arduino Mega But if i try to compile it for my wifi1010 it says
" const int*const index[] redeclared as different kind of symbol"

Thats because SamD boards like the wifi1010 do not use "Progmem" it doesn't need it.
You can simply remove all Progmem code.
EDIT: Ok it may not be that simple but it is what must happen to solve this problem.

Thank you for your reply
i have removed all Progmem , but it still will not compile
It still cmpiles on a Mega but not the Mkr wifi1010.`
