I added some gibberish to the config.inc.php file and i indeed get a
Syntax errors :)

[houtworm@server ~]$ sudo -u http php
/usr/share/webapps/postfixAdmin/public/setup.php
PHP Parse error:  syntax error, unexpected 'ik' (T_STRING) in

In /postfixAdmin only .htaccess is symlinked

in /public only password-change.php and password-recover.php are
symlinked

The config files where both symlinked because i copied local from inc,
i removed both and made new files for them to ensure they are not
symlinked. I did this before but it did not help, Maybe the inc file
needs to be symlinked?

I edited it like this /usr/share/webapps/postfixAdmin/public/setup.php

56 $file_config = file_exists(realpath("./../config.inc.php"));
57 $file_local_config = file_exists(realpath("./../config.local.php"));
58     echo "\n\n file_config: $file_config  local $file_local_config
59 > \n\n";
60 $error = 0;

terminal output

I made the /etc/postfixadmin/ directory and copied config.local.php
into it but the output is still the same

Then finding that file is the only thing that matters, Very strange it
does not see it.

If i can provide any more information please let me know,
