Changing your PHP version with MultiPHP Manager

You can change the PHP version for your whole account or for a single domain directly in cPanel using MultiPHP Manager. Open cPanel, scroll to the Software section, and click MultiPHP Manager. From there you select one or more domains and apply the PHP version you want. The change takes effect immediately for LiteSpeed, with no server restart on your end.

Why the PHP version matters

PHP is the language that powers WordPress and most other dynamic sites. Newer versions such as PHP 8.1, 8.2, and 8.3 are faster and receive active security patches, while older branches eventually reach end of life and stop getting fixes. Running a current, supported PHP version keeps your site secure and can measurably improve response times, which indirectly helps Core Web Vitals. The catch is compatibility: a theme, plugin, or custom script written for an older version may throw errors on a newer one, so you should test after switching.

Change the PHP version for a domain

1. Log in to cPanel and open MultiPHP Manager under the Software section.
2. In the table, tick the checkbox next to the domain or subdomain you want to change. You can select several at once.
3. Use the PHP Version drop-down on the right (labeled "Set PHP Version per Domain").
4. Pick the version you want, for example ea-php82, then click Apply.
5. The PHP Version column updates to show the new value for that domain.

Leaving a domain set to Inherit means it follows the account default. That is convenient, because changing the default later cascades to every domain still set to inherit.

Set the account-wide default

At the top of MultiPHP Manager there is a PHP Version (Currently: ...) control that sets the system default. Choose a version and click Apply to change the baseline for all domains marked Inherit. Domains you explicitly set earlier keep their own version and are not overwritten.

Confirm the change and adjust settings

To verify which version is active, create a small file such as info.php in your document root containing <?php phpinfo(); and load it in your browser, then delete it afterward for security. If a page returns a 500 error after switching, the most likely cause is an incompatible extension or deprecated function in your code. Roll back to the previous version in MultiPHP Manager while you update the offending plugin or theme.

Need to tune limits like memory_limit, upload_max_filesize, or max_execution_time? Use the sibling tool MultiPHP INI Editor, also in the Software section, which lets you edit these directives per PHP version or per domain without touching a raw php.ini file.

Tips for WordPress sites

Before you move a production WordPress site to a new PHP version, update your core, themes, and plugins first, and ideally test on a staging copy. WordPress publishes a recommended PHP version, and staying close to it avoids surprises.
