Failed to load http://xxxxxx.com//assets/i18n/it.json: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:5500' is therefore not allowed access.
This features is already added in v3.1.0. (Sorry, I forget to close it)
It seems like CORS still isn't enabled on the local server. I tested using test-cars.org and returns an error when trying to GET one of the files from the server. Any additional steps I'm missing? Anything that needs to be enabled in the settings?
I still can't access .json files from external domains. Am I forgetting to set something up?

I have also encountered a CORS issue when trying to request a API, are you sure that you have CORS enabled ?
I'm using Safari version 11.1.2
the endpoint is
https://www.cryptocompare.com/api/data/coinlist
Using 5.4.0, I'm getting the same problem when trying to call https://api.flickr.com/services . This is with Firefox.
Same issue here in Chrome, Firefox and Edge on Windows 10.
Is there anything we need to configure before this would work? Thanks!
Edit: I seem to have fixed my issue by simply loosening the CORS settings on my target resource. Now I don't get any errors anymore regarding a missing 'Access-Control-Allow-Origin' header.

Hey I have the same issue when using d3.js. How to fix this issue?
d3.html('http://enable-cors.org')
.get((err, data) => {
console.log(data)
})
