Are you running PHP 7+ ?

Also your base_url needs an ending / slash

What did you Try? What did you Get? What did you Expect?

I added '/' after base_url. But again same error but I am using old PHP.

PHP version 7.0.15 or newer is required, with the intl extension installed. (Documentation)

You need to install PHP 7.+.+ for CodeIgniter 4 it is a requirement.
