-
-* What is monero-wallet-rpc ?
-The monero-wallet-rpc is an RPC server that will allow this plugin to communicate with the Monero network. You can download it from https://getmonero.org/downloads with the command-line tools.

-* Why do I see `[ERROR] Failed to connect to monero-wallet-rpc at localhost port 18080

-This is most likely because this plugin can not reach your monero-wallet-rpc. Make sure that you have supplied the correct host IP and port to the plugin in their fields. If your monero-wallet-rpc is on a different server than your wordpress site, make sure that the appropriate port is open with port forwarding enabled.
