# Help making Captcha non case sensitive

 * Currently the captcha required to submit feedback is case sensitive. Although
   its not a big deal, I would prefer that it not be. Below is the code inside the
   contact form file. I thought it would be as easy as removing “require ‘captcha/
   rand.php’;” from line 8 but that didn’t seem to work. I’m at a lose. Any help
   is much appreciated.
 *     ```
       <?php
       /*
       Template Name: Contact Form

       //@ini_set('session.use_trans_sid', '0');
   
       // Include the random string file
       require 'captcha/rand.php';
   
       // Begin the session
       @session_start();
   
       // Set the session contents
       if (isset($_POST['captcha'])){
       	if($_POST['captcha']!=$_SESSION['captcha_id']){
       		$_SESSION['captcha_id'] = $str;

       }
   
       //If the form is submitted
       if(isset($_POST['submitted'])) {
       	//Check to see if the honeypot captcha field was filled in

 * A custom theme made at wpthemegenerator.com
 * And I never downloaded a plugin. All I did was create a new page and select “
   Contact Form” from the dropdown box on the right.

 * Sorry, but you’re using a premium/paid theme. It’s best to go to the support 
   site where you bought the theme for help with customizations and issues. These
   forums are for themes available in the WordPress theme directory at wordpress.
   org/extend/themes/.
