Codeigniter CORS policy: No 'Access-Control-Allow-Origin' error How to resolve?

Allowing cross-site scripting may cause security issues, try to adjust your codeigniter options;

1. Go to application/config/config.php file,
   
2. find $config['base_url'] = ""; and
   

3. place your project folder's path as value.

    $config['base_url']="http://localhost/yourProjectFolder/";
   

Try allowing GET & OPTIONS

<?php
header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Methods: GET, OPTIONS");

If the above doesn't work, try allowing access to font resources via .htaccess (for apache) or in nginx server block - add these lines:

# Apache config
<FilesMatch ".(eot|ttf|otf|woff)">
    Header set Access-Control-Allow-Origin "*"
</FilesMatch>

or

# nginx config
if ($filename ~* ^.*?\.(eot)|(ttf)|(woff)$){
    add_header Access-Control-Allow-Origin *;
}
