There are two steps to make sure that mutli-language module is actively working on your store.
Step 1: Enabling the module from theme settings
Please go to ocCommerce → Settings admin panel and click on the first tab General Settings. Now in the second option where it says Enable Multi-Language Module please make sure that is Enabled then save changes in your dashboard.
Step 2: Editing wp-config.php file
After enabling the multi-language module, now you need to edit your wp-config.php file to make sure that your store will change the language dynamically based on customer’s choice.
The wp-config.php is located in your WordPress installation/root directory.
Please open your wp-config.php file and add the following bits of code somewhere before the end of the file:
if ( isset( $_GET['lang'] ) ) {
setcookie('WPLANG', $_GET['lang'], time()+3600, '/');
define('WPLANG', $_GET['lang']);
} else {
if(isset($_COOKIE['WPLANG'])) {
define ('WPLANG', $_COOKIE['WPLANG']);
$_GET['lang'] = $_COOKIE['WPLANG'];
} else {
define ('WPLANG', '');
}
}
Save the file and close. Your multi-language module is now active.
