From WordPress 2.6 Version it is possible to change the wp-content folder. First change the wp-content folder. For example to axio
Now put the following code at the beginning of the wp-config.php file, respectively. Before the wp_setting code
define( 'WP_CONTENT_DIR', dirname(__FILE__) . '/axio' );
axio is the name of the new folder to which you changed Wp-content.
And put the following code after the above code:
define( 'WP_CONTENT_URL', 'https://aixo.ir/axio' );
The above code specifies the wp-content address on your site. For example, if for the site Axio name of the wp-content folder to axio for Axio site, the above code should be written as axio.ir/axio.
