Error 404
localhost Apache/2.4.23 (Win32) OpenSSL/1.0.2h PHP/5.6.24
config:
$config['base_url'] = 'http://localhost/1/';
autoload
$autoload['helper'] = array('url', 'form', 'html');
site_url works for me but when I used base_url it doesn't work. I prefer to use base_url() than site_url.
How to run my code?
I think the problem with your config, You can replace
$config['base_url'] = 'http://localhost/1/';
With
$config['base_url'] = 'http://localhost';
Or
$config['base_url'] = 'http://localhost/Yoursite';
Hope this working
