Server is linux, server api is litespeed. i opened the logs. Log is writing only this lines. Normally the lines should continue with "Config file loaded: config/settings.php" line. But codeigniter can't load settings.php. I can't get any printed error at the page. Only white blank page. How can it possible?

When i delete the "settings.php" from autoload.php, the page has been created. I check it from the log file. But page doesn't run correctly. There are too much option in settings.php file. It should load. How can i fix it?

What is settings.php? That's not a core file

[eluser]agresif[/eluser]
settings.php is a config file. i indicate at the autoload.php

Ok...

Any PHP errors should be written to the litespeed error log (/opt/lsws/logs/error.log, possibly) not necessarily the codeigniter log. I would check there. A white screen generally indicates syntax error(s).
