here working code after modifying

change form action 'http://85.195.86.86/index.php/login/index'

and here 'hi!' :)

summery: if want use existing 'url' remove 'index.php' 'url' .htaccess. can serch on google 'how remove index.php in ci'

.htaccess code:

options -indexes options +followsymlinks  rewriteengine on  #removes access system folder users. #additionally allow create system.php controller,  rewritecond %{request_uri} ^system.* rewriterule ^(.*)$ index.php?/$1 [l]  #when application folder isn't in system folder  rewritecond %{request_uri} ^application.* rewriterule ^(.*)$ /index.php?/$1 [l]  #checks see if user attempting access valid file, #such image or css document, if isn't true sends #request index.php  rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule ^(.*)$ index.php?/$1 [l]  # if don't have mod_rewrite installed, 404's # can sent index.php, , works normal. # submitted by: elliothaughin     errordocument 404 /index.php 

ci config file changes:

$config['base_url'] = '';  $config['index_page'] = '';
