PHPExcel Doesn't work when the database library is loaded in /config/autoload.php

[eluser]Unknown[/eluser]
I'm trying to use PHPExcel with codeigniter but I'm having problems when the database library is loaded in the autoload.php file. The example I got from the net works perfectly fine except when the database library is loaded. All I get is a blank page.

Did anybody also encounter this issue? Is there a way to fix this problem? I need to get export data from the postgresql table and I don't see any way to this if I can't use the database library.

Any help would be much appreciated.

A blank page is probably a 500 error being masked by your environment settings error level. Set it to development and it should show you the error message.

The environment setting is already set to development since I started working on it but all I see is a blank page.

EDIT: I finally fixed the problem, I forgot to change the dbdriver from 'mysql' to 'postgre'. It's pretty stupid and clumsy in my part. Thanks for replying to my query.
