Uncaught Error: Class 'Phalcon\Mvc\User\Component' not found

Use \Phalcon\Di\Injectable instead. In v4 class Component was removed.

Hi Anton, the composer.json file has following php version. but am installed php 7.4.6 is there is any issue with our project .. or i want to downgrade the same in the composer.json??

"config": { "platform": { "php": "7.1.3" } }

Phalcon isn't installed via Composer, so this error doesn't depend on Composer, or your PHP version for that matter.

Are you running Phalcon version 3.4 or version 4?

am using 3.4.11 phalcon version, but am facing new issue which is js and css file directory not found. but application runs fine.
