I want to display specific information from a smart contract on the main ether network on a wordpress website i can't seem to be able to do that, all tutorials only show test networks. the smart contract is already running on the ether network.
My recommendation is to try and connect your webpage to something like Infura. (https://infura.io/). They have fantastic tutorials, this question is a bit broad to cover in a single answer to be honest. But looking at Infura should get you started open up a new question if you have trouble with a specific part fo the process or alternatively clearly point us to where exactly you are in the set up process, it is very difficult to help with no details.
