Hello, I have this error:

Intl extension is required to improve internationalization support, such as locale aware sorting and international domain names.

I have tried this:

To enable this extension add the following line to your php.ini file usually found in /php:

extension=php_intl.dll

And then set the intl.default_locale and intl.error_level directives in your php.ini file.

[intl]

intl.default_locale = en_utf8

intl.error_level = E_WARNING

; Notes for Windows environments :

;

; - ODBC support is built in, so no dll is needed for it.

; - Many DLL files are located in the extensions/ (PHP 4) or ext/ (PHP 5+)

;   extension folders as well as the separate PECL DLL download (PHP 5+).

;   Be sure to appropriately set the extension_dir directive.

;

extension=bz2

extension=curl

extension=fileinfo

extension=gd2

extension=gettext

;extension=gmp

;extension=php_intl.dll (I copy this here)

;extension=imap

;extension=interbase

;extension=ldap

extension=mbstring

extension=exif      ; Must be after mbstring as it depends on it

extension=mysqli

;extension=oci8_12c  ; Use with Oracle Database 12c Instant Client

;extension=openssl

;extension=pdo_firebird

extension=pdo_mysql

;extension=pdo_oci

;extension=pdo_odbc

;extension=pdo_pgsql

extension=pdo_sqlite

;extension=pgsql

;extension=shmop

What shall I do?

Thank you
