But i don't have php7.2 installed. I use php7.4. What can i do now? I use Plesk Onyx with Ubuntu18.04. I couldn't find anything at CakePHP documentations. Thanks for your advice.

Answer 1

Install and enable the php intl extension in CLI and "Web" environment. Be aware that you often have two different php.ini. One for CLI (command line) and one for "regular" PHP which runs on top of nginx or apache2.

After changing your configuration be aware to restart you apache2 / nginx or restart the server otherwise your changes have to effect.
