error minting on Polygon

In WordPress we deployed WP Smart Contracts plugin Suika version a couple of weeks ago to Polygon blockchain network. It worked fine with Polygon Testnet, but when we deployed to the Mainnet, when we mint an art it gives error.

Then we use the “Load an Existing Smart Contract” button in WordPress to create a new NFT Collections. It loaded the existing smart contract successfully and created a new NFT Collections. But when we try to mint an art with it, it gives the following error:
An error ocurred during mint
Internal JSON-RPC error. {“code”:-32000, “message”: “execution reverted”}
