You will need to create a file “.htaccess” inside your domain directory (for example: /home/www/yourdomain.ext/.htaccess with the following contents:
RemoveHandler .htm .html
If you have a paid hosting account and you do not want to use or create a .htaccess file to fix the error, go to your Hosting Control Panel -> Hosting Tools -> PHP Settings and edit your php.ini file. Then search for the PHP directive “short_open_tag” and set it from “On” to “Off” and click “Save” to apply the changes.
