Edited

Overview

Upgrading from PHP 7.4 to PHP 8.0 brings significant performance, security, and compatibility improvements to your WordPress site. BionicWP encourages all users to keep their PHP version up to date to ensure the best possible experience and ongoing support.

Use this FAQ to understand what changes with PHP 8.0, what to check before upgrading, and how BionicWP helps manage the process.

How It Works

When you request a PHP upgrade or your site is scheduled for automatic updates, BionicWP will update your site’s server environment from PHP 7.4 to PHP 8.0. This may impact plugins, themes, or custom code that are not compatible with PHP 8.0, so preparation is key.

Frequently Asked Questions

1. What are the main benefits of PHP 8.0?

  • Faster site speed and improved performance

  • Better security features and ongoing support

  • New language features for improved plugin/theme compatibility

2. Will my site break if I update to PHP 8.0?

Most modern plugins and themes are compatible, but older or custom code may not be. Always test in a staging environment before upgrading your live site.

3. How do I check if my site is ready for PHP 8.0?

  • Review plugin and theme compatibility with PHP 8.0 (check developer changelogs)

  • Update all plugins and themes to their latest versions

  • Test on staging and look for errors or warnings

  • Update any outdated plugins, themes, or custom code

5. How do I request a PHP upgrade?

Contact BionicWP support or use the dashboard to request the PHP version change. Our team will schedule the update and monitor for issues.

6. What if something goes wrong after upgrading?

  • Roll back to PHP 7.4 using the BionicWP dashboard or contact support for immediate help

  • Restore your site from the latest backup if needed

7. Is there a cost for upgrading PHP?

No, upgrading your PHP version is included as part of your BionicWP hosting plan.

Pro Tip:
Always keep a staging site up to date and use it to test major updates before rolling out changes to your live environment.
