# Troubleshooting

If you find that no matter what you put in your URL only your default page is loading, it might be that your server does not support the PATH_INFO variable needed to serve search-engine friendly URLs. As a first step, open your application/config/config.php file and look for the `URI Protocol` information. It will recommend that you try a couple alternate settings. If it still doesn't work after you've tried this you'll need to force CodeIgniter to add a question mark to your URLs. To do this open your `application/config/config.php` file and change this:

`$config['index_page'] = "index.php";`

To this:

`$config['index_page'] = "index.php?";`
