FuelCMS vs IgnitedCMS

Paul, although the CMS I'm about to suggest is not based on Codeigniter, I think it may fit what you were looking for. It's lightweight, and it does not have a built-in blogging pattern. It's basically a CMS built upon a bare-bones framework that still manages to include Observer, Dispatcher, Active Record, and View classes. Also, extending the CMS itself is easy. Anyway, it's called Wolf CMS http://wolfcms.org/ For actual applications, I use Codeigniter, but for websites that just display information, I much prefer Wolf over WordPress.

Hey, don't work without a PHP debugger. Several free IDEs have this features built in. Two are NetBeans and CodeLobster. Without a debugger, it's like you're driving with a blindfold on -- you are going to crash!
