From today (the 7th of June 2018) PHP 7.2 is available in our Service Center. Log in as webmaster in the Service Center and got to Hosting > Management and adjust the PHP version to PHP 7.2 for your entire hosting package. On our helpdesk pages you will find a manual on how to change this setting: https://greenhost.net/helpdesk/website/hosting-management/PHP-version/.
After switching the PHP-version, we recommend to check for any problems immediately. There is a small chance that you are experiencing some problems due to deprecated functions on your site(s). We also advise to immediately update your CMS (Content Management System, for example WordPress or Joomla) and all plug ins you may have installed.
The PHP versions 5.6 and 7.0 will because of security reasons be faced out throughout the year.
