Here are some common installation problems, and suggested workarounds.
I have to include index.php in my URL¶
If a URL like /mypage/find/apple doesn’t work, but the similar URL /index.php/mypage/find/apple does, then your .htaccess rules (for Apache) are not setup properly.
Only the default page loads¶
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 REQUEST_URI variable needed to serve search-engine friendly URLs. As a first step, open your application/Config/App.php file and look for the URI Protocol information. It will recommend that you try a couple of 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/App.php file and change this:
public $indexPage = 'index.php';
public $indexPage = 'index.php?';
