Q: I get URL not found issue error using codeigniter in Ubuntu 14.04 I have integrated my codeigniter project with Ubuntu 14.04. It was giving me url not found errors after the default controller, which is login controller.
Please find following .htaccess file
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /myapp/

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Submitted by: Fabdrol
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.

    ErrorDocument 404 /index.php
</IfModule>  


A: Ok you first need to enable mod_rewrite
sudo a2enmod rewrite

sudo service apache2 restart

then open apache conf file
sudo gedit /etc/apache2/apache2.conf

uncomment this line if it is commented
AccessFileName .htaccess

you need to change AllowOverride  to All - note my root is var/www/html yours might be just var/www
<Directory /var/www/html/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted


Restart apache and that should do the trick
sudo service apache2 restart
