To fix the "Fix Internal JSON-RPC Error in Metamask, start by ensuring your MetaMask extension or app is up to date, as outdated versions can cause compatibility issues. Clear the cache or reset the account within MetaMask (this won’t delete your funds but will refresh your transaction history). If the error persists, check the network settings to confirm you’re connected to the correct blockchain (like Ethereum Mainnet or Binance Smart Chain). You may also need to add more gas or adjust transaction parameters. Finally, if none of these steps work, try switching to a different RPC URL or contact MetaMask support for further assistance.
