Why Aren't My CodeIgniter URLs Removing 'index.php' Despite Using mod_rewrite?

Removing index.php from CodeIgniter URLs

Your goal is to eliminate "index.php" from your CodeIgniter URLs, but despite enabling mod_rewrite, setting $config['index_page'] to '', and implementing the provided .htaccess code, the issue persists. Let's investigate the potential causes.

To begin, ensure that mod_rewrite is enabled in your Apache2 server configuration and that the $config['index_page'] variable in config.php is empty:

$config['index_page'] = "";

Next, verify that your root .htaccess file contains the following code:

RewriteEngine on
RewriteCond  !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/ [L,QSA]

Note that .htaccess code may vary depending on your hosting server. In some cases, an additional "?" may be required at the end of the last line:

RewriteRule ^(.*)$ index.php?/ [L,QSA]

If the previous steps fail to resolve the issue, try the following:

1. Enable REQUEST_URI Protocol: Replace $config['uri_protocol'] = "AUTO" with $config['uri_protocol'] = "REQUEST_URI" in config.php.
2. Disable RewriteEngine During Development: Apache2's RewriteEngine can interfere with CodeIgniter's development environment. Disable it temporarily by commenting out the RewriteEngine line in your .htaccess file during development.
3. Check .htaccess Permissions: Ensure that the .htaccess file permissions are set to allow Apache2 to modify them.
4. Clear Cache: Close and reopen your browser or clear its cache to ensure the new URL structure is recognized.
