Administration - Installation - Core: Re: I've managed to downgrade but no luck

Hello Jakub,

it looks to me like an 'incomplete' ILIAS codebase folder.
The PHP-Warning states: ... no such file or directory in /var/www/html/setup/cli.php ... ,
so I assume your local codebase folder - where you checked out or unpacked ILIAS - is:
  /var/www/html/
, right?

If the codebase would be complete, then there must exist:
  /var/www/html/include/inc.ilias_version.php
or, in an equivalent path coding:
  /var/www/html/setup/../include/inc.ilias_version.php
(as written in Warning and Fatal Error).

Check this!

Best regards.
