CodeIgniter 500 Internal Server Error
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.
You're trying to remove index.php from your site URL's, correct?
Try setting your $config['uri_protocol'] to REQUEST_URI instead of AUTO.
The problem with 500 errors (with CodeIgniter), with different apache settings, it displays 500 error when there's an error with PHP configuration.
Here's how it can trigger 500 error with CodeIgniter:
- Error in script (PHP misconfigurations, missing packages, etc...)
- PHP "Fatal Errors"
Please check your apache error logs, there should be some interesting information in there.
