Cannot login at Manifold Studio + Json file error

Hi.

  1. When I tried to update my burn-redeem token’s end date, following error appeared several time and I couldn’t update the contract. :
    " Unexpected token ‘<’, "<!DOCTYPE "… is not valid JSON "

  2. So I disconnected with Manifold app and tried to log in again, but I cannot login with my wallet.
