In this article, we will provide information about our special feature PHP Extended Support.

What is PHP Extended Support?

PHP is a very powerful programming language that is used to create dynamic websites.The PHP community regularly releases new, improved versions of PHP and discontinues support for previous versions at a specific times.Since the older version no longer receives security updates, it should no longer be used.

In order to give you more time to change to a current PHP version, we offer PHP Extended Support.

In PHP Extended Support, IONOS fixes security vulnerabilities in the affected, discontinued PHP versions as they are discovered.It is our goal to provide you with an uninterruptible service for your online projects while also preventing your websites from becoming vulnerable to hackers.Your PHP projects and scripts will stay the same while being protected from attack until you decide to upgrade to a current PHP version.

As part of the PHP Extended Support, IONOS security experts ensure that security vulnerabilities affecting older PHP versions continue to be closed. Your PHP projects and scripts will remain protected from attacks until you decide to switch to a current PHP version. Maintaining the old PHP versions means an increased administration effort on our systems. We charge you a monthly fee for this additional service.

Important Information for PrestaShop Users

PrestaShop versions up to and including 1.7.8 installed through the IONOS AppCenter do not work with PHP versions 7.4 and higher.

Action required: Update your PrestaShop installation. PrestaShop 8.0 supports PHP 8.0 and 8.1. No change required to your PrestaShop installation. Keeping the PHP version requires PHP Extended Support, which will be a paid feature starting in April 2023 for version 7.4. A recent PHP version, such as 8 or 8.1, is required.

Important: Make sure you back up your webspace data and MySQL database(s) before performing any changes.

Log in to your PrestaShop administration panel and click on any item in the navigation. Scroll the screen content until you reach the bottom edge. On the left is the version number of your PrestaShop version.

If PrestaShop 8.0 is already installed, you can also click Settings > Advanced settings > Information to view the version.

Updating PrestaShop

PrestaShop is an independent, open-source program for which IONOS does not offer any direct support. You can find more information on how to update PrestaShop below:

Why am I being charged for PHP Extended Support?

We found PHP content in your webspace in an old, no longer supported PHP version. You may have connected at least one domain of your hosting contract to an outdated version of PHP. If you want to change this setting for each domain, please click here to go to your PHP Settings Overview. Select the domain and click Configure PHP Version. Choose the PHP version you would like to use and click Save.

We recommend that you always use a current PHP version. This will ensure that you can use the most popular and proven applications without further compatibility problems.

PHP Extended Support in Managed WordPress contracts

To ensure that Managed WordPress websites are always up-to-date and secure, our experts regularly check and update not only the WordPress installation, but also the PHP version used. So you don't have to worry about updating the PHP version as it is always up to date.

Nevertheless, if we inform you through the use of an outdated PHP version or you are already being charged for PHP Extended Support, please check the following:

  • Do you have WordPress installed in the default version? Möglicherweise handelt es sich um eine zusätzlichen WordPress-Installation, oder Sie haben eine Managed WordPress-Installation in eine Standard-Installation geändert.
  • Have you set up a domain or subdomains that are not connected to a Managed WordPress installation, a website builder from IONOS or external service?

You can find out how to find out which PHP version your domains are configured with and how to update the PHP version here.
