apache - Codeigniter - removing index.php causes links to break -

i experiencing issue index.php in url whereby when removed links controller no longer working ?

i have modified following:

config.php:

$config['index_page'] = ''; 

uri protocol was:

$config['uri_protocol'] = 'request_uri'; 

.htaccess:

rewriteengine on rewritebase /ampp/ rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule ^(.*)$ index.php/$1 [l] 

i have verified phpinfo(); module mod_rewrite loaded.

current url in format: http://localhost:100/ampp/

the login form on main page:

<form class="form-signin" method="post" action="<?php echo site_url('auth/login') ?>">     <span id="reauth-email" class="reauth-email"></span>      <input type="email" id="inputemail" class="form-control" placeholder="email" name="email" required autofocus>     <input type="password" id="inputpassword" class="form-control" placeholder="password" name="password" required>     <br>     <button type="submit" name="submit" value="submit" class="btn btn-lg btn-primary btn-block btn-signin">sign in</button> </form> 

however when submit form getting 404

not found  requested url /ampp/auth/login not found on server. 

i have checked log files see problem log files indicate auth not found.

file not exist: /var/www/html/ampp/auth, referer: http://localhost:100/ampp/ 

technically file not located in directory log files claiming (which true file in /ampp/application/controller/) have thought codeigniter resolve appropriately.

.htaccess check

i thought give go , seems problem actual .htaccess file. why?

well have replaced content of .htaccess file this:

order deny,allow deny 

yet still able view main login page (despite fact .htaccess should not allow me)

update: ok since have noticed .htaccess file not working went digging find out why not working.

and result issue vhost configuration...

<directory "/"> //<-------- issue.     allowoverride     order allow,deny     allow </directory>   <directory "/var/www/html/ampp"> //<------- has resolved issue.     allowoverride     order allow,deny     allow </directory> 

i assuming auth controller class , login method of class. check filename of class file i.e. check filename of auth controller, should first character uppercase, "auth.php". , change action of form to

site_url('auth/login') 

note: auth lowercase in url.

hope solve problem.
