Hello, Steve. Congratulations for your wordpress, has a lot of interesting information.
Well, I'm trying to use this code of yours, but I can't make it work, even using my own API key. There is no error, but the output is "null" for every language. See the gh file here https://drive.google.com/file/d/1-5MnDdxnfGPBH7dbM9ZxStq47xvlo-SR/view?usp=sharing.

Hope you can give me an idea of how to fix.

Thanks you in advance,
Kevin

I think google discontinued supporting their translate service several years ago
