What does this FAQ entry answer?

This page tries to cover some of the questions we think you may ask, or which we have received questions about. We will update it as necessary.

What is the difference between the old and new webservers?

The operating system on all new webservers are running Ubuntu 20.04 LTS, the old ran Debian 9 Stretch.

What is the difference between the PHP 7 versions?

There are no big changes between different PHP 7 versions on our servers. Check the PHP documentation for your version for detailed information about the changes:

The PHP-configuration for 7.x is nearly the same as 5.6. Notable differences:

  • If your CMS (e.g. Drupal, Joomla!, WordPress) has not been updated in years, you may get an error message about "mysql connection", "mysql driver", or "mysqli driver", because the CMS is incompatible with PHP 7. Upgrade to the current version.
  • IonCube Loader can be activated from the control panel for your web hosting. It will not be possible to use your own php.ini if you activate these services. This is a preferred option compared to using user-created php.ini files and other additions.
  • Zend Guard Loader is officially discontinuted as of PHP 7.0.

Which applications/services will have trouble running on our PHP 7.x webservers?

Most programs and additions that ran on PHP 5.6, will run on PHP 7 as well. Check with your program provider to make sure your software is supporting PHP 7.

You may see an error message about MySQL, "mysqli" etc. if you have an old php.ini, this file must then be removed.

Regarding self-developed code, check PHP-documentation for what changed that is not backward-compatible with PHP 7.

If you are running self-written modules or additions in PHP 5.6 you will most likely have to upgrade them to be compatible with more recent PHP versions (7.x). This includes (in most cases) IonCube Loader. Support for IonCube Loader is recommended to be activated via the control panel for the web hosting.

Can I switch between the different PHP versions?

Yes, you can freely switch between different versions.

Please note that the version changes may take up to 20 minutes.

When we announce that we're no longer supporting a specific version, you can no longer select that specific version.

Can I test/use PHP 7 on SSH?

Yes. You can use This shell server automatically provides the same PHP version that you have chosen for your web hosting.

How long will you support PHP 7?

We will support the various versions approximately as long as PHP offers security updates, but will start phasing out before security support ends.

We ceased offering PHP 5.6 and PHP 7.0 on 12 December 2018, ceased offering PHP 7.1 on 1 December 2019, ceased offering PHP 7.2 on 2 November 2020, ceased offering PHP 7.3 on 6 December 2021, and ceased offering PHP 7.4 30 November 2022.

For other versions, please follow the link, and plan upgrades in good time. Our plans may change if PHP changes their plans regarding security updates.

My PHP-program is not working. Why?

Check How can I see PHP errors/debug PHP code? for additional help.

If you are using WordPress, activate error logging as described above. In most cases, the error messages will contain information about a WordPress plugin causing issues. This plugin can then be deactivated by deleting or renaming the plugin folder via FTP. See here for an explanation.
