I am trying to obtain data from a JSON, in local mode I can make it work, I have to enable a CORS extension in chrome and that’s it.
Then when I have decided to upload the file to the server, on the server side with PHP, I enable the headers as follows

<?php
header("Access-Control-Allow-Origin: *");
?>

y tambien en el .htaccess de la siguiente manera:

 <IfModule mod_headers.c>
   Header set Access-Control-Allow-Origin "*"
 </IfModule>

Access to XMLHttpRequest at 'https://www.siteExample.com/coins/151.json?hr=100' from origin 'https://meSiteExample.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

What else can I do?

As I read here, Maybe you need use:
```
Header add Access-Control-Allow-Origin "*"
```
Instead of :
```
Header set Access-Control-Allow-Origin "*"
```
in your .htaccess file.

Also Remember & pay attention '*' will enable CORS for all websites. and it has security risks. if you know your request coming from where , you can filter that by enter domain instead of '*'.

For example:
```
Header add Access-Control-Allow-Origin "example.com" //OR "localhost"
```
