In this article, we show you step-by-step how to fix issues on your website caused by the latest PHP update. They are most likely due to an incompatible plugin and theme.
- Step 1 - Revert the PHP update
- Step 2 - Update your CMS (f.ex. WordPress)
- Step 3 - Change the PHP version back to 8.2
- Step 4 - Check your site
Step 1 - Revert the PHP update
First, we recommend you manually change the PHP version back to 8.0, following these steps:
- Log into your one.com Control Panel.
- Scroll down to the Advanced settings tile and select PHP and database settings.
- Scroll down to Update PHP version.
- Select version PHP 8.0 and click Update.
Step 2 - Update your CMS (f.ex. WordPress)
When your website is visible again, the most important next step is that your CMS is up-to-date.
The core installation and all plugins, themes, extensions and additions must be set to the latest version.
Your website is likely made with WordPress, the most used CMS in the world. That's why we have elaborated the steps for WordPress here below.
Check our specified guide if your website is made with Joomla or other commonly used CMS such as Drupal or Prestashop. Please keep in mind that we cannot fix (custom) code for you. You must either do this yourself or find a developer familiar with PHP who can help you.
- Log into your WP Admin.

- When logged in, click Updates in the menu to the left.
- A red dot with a number indicates that updates are available and how many.
That red dot has to go. To get this done, you need to make sure that:
- You have the latest version of WordPress.
- Your Plugins use the newest version.
- Your Themes use the newest version.
Important! Remove plugins and themes that you don't use. Find an alternative and replace those that haven't been updated in a while or where there's no update available.

Step 3 - Change the PHP version back to 8.2
Now that the core and all plugins, themes, extensions and other additions of your CMS are up-to-date, try PHP version 8.2 again.
Follow once more the steps of step 1 of this guide. Then continue with step 4.
Step 4 - Check your site
When your PHP version is set to 8.2, check if your site still works.
Yes, my site works
Great, your CMS is successfully updated and compatible with PHP version 8.2.
We recommend that you keep an eye on new updates and act proactively when they appear so your website is ready for the next PHP update.
