Have you done any modifications to your /system folder and/or installed something new?
Have you added a new route in config/routes.php? That somehow breaks free and breaks your core/Router.php.

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
$route['posts/create'] = 'posts/create';
$route['(posts/(:any)'] = 'posts/view/$1';
$route['posts'] = 'posts/index';
$route['default_controller'] = 'pages/view';
$route['(:any)'] = 'pages/view/$1';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
This is the code. How can I fix this
RE: preg_match(): Compilation failed - jreklund - 01-25-2020
I'm guessing it's this guys fault: $route['(posts/(:any)'] = 'posts/view/$1';
It should be: $route['posts/(:any)'] = 'posts/view/$1';
If it still dosen't work. What version of CodeIgniter do you use? And have you done any modifications to the system folder?

I found a problem when go for edit a post.. Then wrongly redirect to http://localhost/ciblog/posts/posts/edit/Post-One rather http://localhost/ciblog/posts/edit/Post-One. That's why it is found that 404 Page Not Found. It may be caused by wrong link.. Someone please help to check following codes.
