Today I happen to come across an issue with codeigniter where the homepage worked fine, however inner pages showd error 404. Details of the issue were as follows:
- Homepage loaded fine.
- Homepage with index.php in url also loaded fine
- Subpages didn’t load with direct url, e.g. /about
- Subpages worked fine when loaded with index.php in url, e.g. /index.php/about
How to solve codeigniter 404 error on inner pages
We solve it by following these steps and making sure that everything is fine.Make sure that mod_rewrite is enabled: you can check that by creating a file named info.php and adding this code to it:
<?php
echo phpinfo();
Look for mod_rewrite on this page and make sure that it is installed as is in enabled modules list.
If not, then uncomment it in this file:
/etc/httpd/conf.modules.d/00-base.confhtaccess code for codeigniter
Secondly, make sure that .htaccess is present in the document root folder and has necessary code in it. This is the default htaccess code for codeigniter:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
If this still don’t work, then make sure that AllowOverride is enabled in httpd conf.
Goto:
/etc/httpd/conf/httpd.conf
Edit this file and find block for /etc/www/html directory and make sure that AllowOverride is All (not none), like this:
<Directory "/etc/www/html">
AllowOverride All
</Directory>
You’ll have to restart httpd after making changes to this file.
Restart httpd by:
sudo service httpd restart
I hope this solves your issue. If you’re still unable to load sub pages of codeigniter website and it shows error 404, please let me know.
