Cross-Origin Resource Sharing (CORS) Problem in Codeigniter

Facing a problem with CORS while developing a web with Codeigniter, the console keeps giving this error message "...has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource"

I browsed and tried many solutions posted in web, many failed to solve my problem. Finaly, I found a solution that works, at least for me. This is the link, where I found the solution. Link

So this is the solution:

Open "config.php" which is located in ../application/config/config.php .
Under Base Site URL, change existing configuration with this:

$config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http");
$config['base_url'] .= "://".$_SERVER['HTTP_HOST'];
$config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);

This works like a charm....
Hope this can help you somehow...
