I have this problem also, as soon as I load or autoload the database, my CI 2.1.3 install white screens. CI works like a charm on my localhost wamp setup. On my shared linux hosting, blank pages. (unless I don't load the DB, then I get the 'Welcome')
I'm not a server admin, but from what I can see it should be able to run CI. I've had every major CMS on this host run in the past few years. Wordpress, Joomla, Pligg, etc.. They all make heavy use of mysql, so I'm stumped as to why loading the database with CI is causing it to http 500 with a blank page. I also run phpmyadmin on this same host and it is fine.
This is a blank vanilla install with CI 2.1.3. Not one line of custom code yet.
PHP Version 5.2.12
Mysql Client API version 4.1.10a
My config file is correct. In fact if I run this app on my localhost using the same DB credentials, I am actually able to connect to my remote hosting database and insert and read data!
I'm stumped
