Installation problem. No autoload_psr4.php

[MaDamO]

Hello,

I wanted to install Joomla on the new server and here's a surprise. The first screen and the problem:

Code: Select all

An error has occurred while processing your request.
0 Failed opening required '/var/www/html/joomla/administrator/cache/autoload_psr4.php' (include_path='.:/usr/share/pear:/usr/share/php:/usr/share/pear:/usr/share/php')

Code: Select all

# php -v
PHP 8.1.11 (cli) (built: Sep 28 2022 09:08:05) (NTS gcc x86_64)
Copyright (c) The PHP Group
Zend Engine v4.1.11, Copyright (c) Zend Technologies

# ls
Joomla_4-2-3-Stable-Full_Package

# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

I read on the web that autoload_psr4.php should be generated automatically during the installation process. However, when I check the path, it is not there. php.ini - in the original, I didn't change anything there.

Perhaps someone met with such a mistake and fought it?

Thank you in advance for any suggestions.

Code: Select all

# ls

The name of the package is different from the usual Joomla_4.2.3-Stable-Full_Package.zip. Where did you download Joomla 4.2.3 from?
