Problem with minting button

Hello !

I tried to used this for a whitelist mint and I do all good in devnet. But when I tried to did it in Mainnet, the mint button was desactivated (in grey). I'm really sure the whitelist API was in cause and I don't know how. Maybe it came from my cvs file, but i check it in heroku and it was perfect. If somebody have cross the same problem I'd love to have solutions
