An Unexpected HTTP Error occurred during the API request.

I have read many topics on this but am still having a lot of trouble! Sorry, am a novice! ??

Anyhow, I am trying to install a plugin and this “An Unexpected HTTP Error occurred during the API request.” is the message I keep receiving.

I don’t quite understand how you navigate to your WordPress Installation folder. As well as not knowing how you even edit it.

I can probably change the HTML but am not sure how you get to editing it. Anyone know of a video tutorial or a picture tutorial??

Please help!
