    “plugin requires at least PHP 5.4.0 to work properly.
   You server is currently using PHP 5.3.28.”

 * It’s the version of PHP that is being used on your web server that’s being referred
   to, rather than what might be on your local Mac. I see this in your sites server
   response: `X-Powered-By PHP/5.3.28`
 * It’s likely that your host offers newer versions of PHP for use on your site.
   Contact your hosts support group or browse their FAQ for information on how to
   change the version of PHP your site uses. It’s usually something as simple as
   just adding a line to your .htaccess file, or changing the default version value
   from a drop-down menu in the PHP configuration options of your control panel.
