As of today, April 4, 2017, we are no longer supporting the PHP 5.3.x family of PHP. All client websites have been migrated to a newer version of PHP, and PHP 5.3.x has been retired from our servers. PHP 5.3 was a very old, deprecated version of PHP, and contained many vulnerabilities that decreased the security of your website.
As of this writing, we currently support PHP 5.6.30, and PHP 7.0.18. Our team regularly checks for and applies patches to our PHP system, and minor upgrades to PHP (for example, 5.6.30 -> 5.6.31) are performed without public notification.
By default, most sites are running on PHP 5.6.x, while a few clients have chosen to utilize PHP 7.0. If you wish to have your site upgraded to PHP 7.0, please feel free to open a support ticket (https://www.nerdsonsite.com/blog/2013/03/20/how-to-get-help-support-for-your-business-hosting/) and our team will be happy to help!
