This article explains how to update the PHP of a DreamPress site. If you installed WordPress using the panel installer or manually installed WordPress, view the following article instead for instructions on upgrading the PHP version:
Preparing your DreamPress site for a PHP upgrade
If a DreamPress staging website is already in use, make sure to publish any changes you wish to keep before working on the staging site.
Please note that while following this checklist can help minimize issues, it is important to be aware that due to the vast number of themes, plugins, and customizations available in WordPress, there is always a slight chance of encountering errors or issues during the PHP upgrade process. In such cases, you can attempt to downgrade to the previous PHP version.
These steps are not mandatory, but they are highly recommended for maintaining the security and smooth functioning of your site:
- Check for any pending updates in your DreamPress admin dashboard. Keep in mind that DreamPress installations are configured to update automatically.
- Identify and review older themes or plugins that haven't been updated by the developer in over a year. Consider finding suitable alternatives or contacting the developer for updates.
- Verify if you have any paid themes or plugins with expired licensing for updates. Renew the licenses or explore alternative options.
- If you have customizations written in PHP, it is recommended to have a developer review them for compatibility with the new PHP version.
Testing the upgrade using a staging site
A safe way to test the new PHP version is to create a staging website. This staging site will duplicate your existing live website, allowing you to run tests to see how it reacts to the new PHP version.
If nothing unusual happens, you can upgrade your live website. View the following article for information on how to create a staging website for DreamPress:
Viewing the PHP version of a DreamPress site
