Codeigniter send email error 404 on web page

Question

I'm testing a web example... I create a contact form on this direction, you can try to send an email and then view inspect-console or inspect-network:

http://www.novaderma.cl/site2/

It gives an error 404, "the requested URL was not found on this server" ...I don't know what's happening...here is the .htacces file, please help me !!

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
   RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php/$1 [QSA,L]
</IfModule>

Answer 1

In htaccess file in the root directory add this rewrite rule

<IfModule mod_rewrite.c>

    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d

    # Rewrite all other URLs to index.php/URL
    RewriteRule ^(.*)$ index.php?url=$1 [PT,L] 

</IfModule>

Also in codeigniter Config folder -> autoload.php file add url helper:

$autoload['helper'] = array('url');

Answer 2

You have to use below the code in your htaccess file...

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteBase //
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
