CodeIgniter 500 Internal Server Error

I downloaded a PHP script written using CodeIgniter. when I run it from the localhost, on going to the admin folder, it shows localhost again. Also when running from my web host, it shows a 500 Internal Server Error.

I run the site from http://localhost/myproj It works. Then when I try to go to the admin page which is at http://localhost/myproj/administrator, it gives a 500 Internal Server Error.

I read here that this might be due to a wrong code in the .htaccess file. This is my present .htaccess file

RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/$ $1 [L,R=301]

RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php/$1 [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]

# Without mod_rewrite, route 404's to the front controller
ErrorDocument 404 /index.php

Please help me. I know it might be a very small problem, but I'm unable to find the error.

If your are using local server, this problem is faced in Wampserver when the essential modules are not enable.

You can Enable them with:

Left click on Wampsever icon

Go to APACHE -> APACHE MODULES

scroll down and find "rewrite_module" and "headers_module"

Then mark them check

It will restart automatically. Done.

Pretty late to the party but, i think the best approach to 500 internal server errors in CodeIgniter would be to enable the error log functionality in the Config.php file in the config folder and set a threshold value i.e. $config['log_threshold'] = 1,2,3,4 depending on the logs you want to view.

Make sure your root index.php file has the correct permission, its permission must be 0755 or 0644

This works fine for me

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule >

Try this to your .htaccess file:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule >

if The wampserver Version 2.5 then change apache configuration as

httpd.conf (apache configuration file): From

#LoadModule rewrite_module modules/mod_rewrite.so**

To ,delete the #

LoadModule rewrite_module modules/mod_rewrite.so**

this working fine to me

I know I am late, but this will help someone.

Check if rewrite engine is enabled.

If not, enable rewrite engine and restart server.

sudo a2enmod rewrite
sudo service apache2 restart

This probably isn't relevant any more to this thread, but hopefully helpful to somebody. I've had 500 errors for the past hour as I had a controller return an array not supported by the php version ran on my (crappy) server. Seems trivial but had the hallmarks of a codeigniter error.

I had to use:

class emck_model extends CI_Model {

    public function getTiles(){

        return array(...);

    }

}

Instead of

class emck_model extends CI_Model {

    public function getTiles(){

        return [...];

    }

}

Cheers

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.
