I think you have to add it to cpanel.Because wordpress is already handled then by Apache.
If you want this..it is how you can do..
First, lets be clear about what Apache-Handler is: it is a means of telling the Apache software how to process a given type of file. By default, Apache only handles certain file types. You can configure Apache handlers for other file types using cPanel.Apache handlers control how your site’s Apache web server software manages certain file types and file extensions. Apache comes configured to handle CGI scripts and server-parsed files. Their file extensions include: .cgi, .pl, .plx, .ppl, .perl, and .shtml
You can configure Apache to handle a new file type with an existing handler by manually adding the handler and extension to cPanel. For example, to have the server treat files with the extension .example as CGI files, you would type “cgi-script” under Handler and “.example” under Extension(s).
Adding an Apache Handler
Step 1. Enter the handler name into the Handler field. The built-in handlers are as follows:
default-handler: Sends the file using Apache’s default handler for static content.
send-as-is: Sends the file with HTTP headers as they are.
cgi-script: Handles the file as a CGI script.
imap-file: Parses the file as an imagemap rule file. For more information, see Apache’s documentation.
server-info: Retrieves the server’s configuration information.
server-parsed: Parses the file for server-side includes.
server-status: Retrieves the server’s status report.
type-map: Parses the file as a type map file. For more information, see Apache’s documentation.
Step 2. Enter the file extension in the Extension(s) field.
You may enter more than 1 extension at a time. Simply separate each entry with a space. A file extension is made of the letters after the dot (“.”) in a file name. For example, filename.fileextension
Step 3. Click Add.
This concludes how to add an Apache handler in cPanel
