Why doesn't the site work on Opencart 3 after transferring to the server?

Question

opencart

Hello. Today I moved the store to OC3 on the server, but it does not want to start. 500 error. Although the admin is working. Are there any differences when transferring from 2.x versions?

Answer 1

Look at the logs, who knows what exactly the problem is.

Answer 2

Turn on the error display output and it will become clear, for example, in the index.php file, write
ini_set('error_reporting', E_ALL);
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
if there is no way to see the logs for example)
