Hello, @lalkajitamang

Have you tried to install the intl package directly using apt-get? You can try doing so using the following command:

sudo apt-get install -y php-intl

You can then check if the extension is installed using this command:

php -m | grep intl

If you see the extension listed but you’re still getting an error it’s not loaded you can create an info.php file and check if it’s loaded. If it’s not you can open the main pph.ini file or the one that the website is used and add the following line:

extension=intl.so

Let me know how it goes.

Regards,
Alex
