Website access error

When I try to access https://www.ebizcoach.ca (I am one of the administrators for the site), I receive the following ‘page’ return:

<?php
/**
* Front to the WordPress application. This file doesn't do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/

/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp-blog-header.php' );

I originally was not able to get into wp-admin, but I was able to finally get in by following the updates to the plugin folder as shown below:

How to deactivate all plugins when not able to access the administrative menus?
Sometimes it may be necessary to deactivate all plugins, but you can’t access the administrative menus to do so. One of two methods are available to deactivate all plugins.
Use phpMyAdmin to deactivate all plugins.
1. In the table wp_options, under the option_name column (field) find the active_plugins row
2. Change the option_value field to: a:0:{}

Or reset your plugins folder via FTP or the file manager provided in your host’s control panel. This method preserves plugin options but requires plugins be manually reactivated.
1. Via FTP or your host’s file manager, navigate to the wp-contents folder (directory)
2. Via FTP or your host’s file manager, rename the folder “plugins” to “plugins.hold”
3. Login to your WordPress administration plugins page (/wp-admin/plugins.php) – this will disable any plugin that is “missing”.
4. Via FTP or your host’s file manager, rename “plugins.hold” back to “plugins”

I logged into the FTP site followed the process above and I am now able to get into the admin area.

However, I am still getting the original ‘page’ returned above.

Any ideas on what I can do to get this fixed so access is returned? The site was working fine until the upgrade to WordPress v4.7.2.

Frustrated,
