Refer following steps to change your PHP server type  from PHP5/PHP to FCGI:
1. Go to your hosting directory “public_html” or htdocs or root directory where your website index.php is located.
2. Create a new .htaccess file.
3. Edit this AddHandler on the top of the .htaccess file: AddHandler fcgid-script .php
4. Get rid of any line such as: AddHandler application/x-httpd-php5s .php
That’s all, your php scripts are now executed with FCGI which is much faster and saves your memory too!
