Answer 1

Just in case somebody else stumbles across this problem, I inherited an older CodeIgniter project and had a lot of trouble getting it to install.

I wasted a ton of time trying to create a local installation of the site and tried everything. In the end, the solution was simple.

The problem is that older CodeIgniter versions (like 1.7 and below), don't work with PHP 5.3. The solution is to switch to PHP 5.2 or something older.
