I am trying to deploy a contract using Remix IDE and Metamask. But whenever I try to create to deploy the contract I get the error

Cannot create an account: Error: Internal JSON-RPC error.

I am using Injected web3 and have followed every step on here:

Can anyone direct me as to why this is happening?

It depends on where you point your RPC connection. It was probably a local instance of TestRPC/Ganache, which has been bugging like that lately. Just restart it and make sure you tell Metamask the correct port. If it's the Ropsten/Main Network, try restarting your Browser.
