If you’re reading this then you’re in the same board as me. I had tried Googling and trying different directives in .htaccess file, I even went and edited the httpd.conf file which is the Apache configuration file in case you didn’t know. Nothing worked.
Finally I asked the Senior Admin and then solution was simple. Follow the instructions below.
Login to your website FTP.
Make a file called .htaccess in case it’s not there yet. Needs to be in root folder, such as /public_html/.htaccess
If you’re using PHP 5.5
AddType application/x-httpd-ea-php55 .html .htm .php
If you’re using PHP 5.6
AddType application/x-httpd-ea-php56 .html .htm .php
If you’re using PHP 7.0
AddType application/x-httpd-ea-php70 .html .htm .php
If you’re using PHP 7.1
AddType application/x-httpd-ea-php71 .html .htm .php
Now, I haven’t tested this on PHP 7+ but I am assuming the directives would be the same.
This works on Apache EA4 Linux. If you have any issues, use the comments below and I will help you out as best as I can.
