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!

How to enable Directory Browsing?

You need to create a .htaccess file and include following code:
Options +Indexes

Upload the .htaccess file to the folder where you wish to have files should be listed in browser. By doing this, all the files in the directory will be listed as you see them in FTP or FileManager.

Your users can only see the list of files and they cannot edit it or make changes. So no worries.

Example:
Parent Directory
index.htm
image.jpeg
em.mp3
htaccess.txt
————————————————————
To disable the Directory browsing, just add:
Options -Indexes
(replace)
OR
Remove .htaccess.
