The config.php file could not be found

[SuicidalMedia]

No,
It should be just URL, e.g. mydomain.com/forum

Sry I was not precise.

In server_name is my real adress mydomain.com.

My forum is in root httpdocs.

Hold on have you tired just simply reuploading config.php or making a new one it seems like it has corrupted the fact that its asking for a re install means it cant read the config.php at all let alone get into the database so i doubt anything will be wrong their

If you want to create a new one just make a new config.php and it should have this in it fill in your details

<?php
// phpBB 3.0.x auto-generated configuration file
// Do not change anything in this file!
$dbms = 'mysqli';
$dbhost = '';
$dbport = '';
$dbname = 'db name goes ere';
$dbuser = 'db username goes here';
$dbpasswd = 'db password goes here';
$table_prefix = 'phpbb_';
$acm_type = 'file';
$load_extensions = '';

@define('PHPBB_INSTALLED', true);
// @define('DEBUG', true);
// @define('DEBUG_EXTRA', true);
?>

And make sure you give it chmod perms of 644

Thanks all for try to help me.

I create new config.php 5 times and checked 50 times and no work.

I do not know why but report as the file does not exist and of course is there.
