How to change PHP version with MultiPHP Manager in cPanel

When a plugin or theme breaks, changing the domain PHP version is usually the first safe adjustment to recover site stability.

Before you start

• Identify which domain is showing the issue.
• Keep a recent backup of files and database.
• Confirm the PHP version recommended by your CMS or plugin.

Steps

1. Sign in to cPanel and open MultiPHP Manager.
2. In Set PHP Version per Domain, select the domain you want to adjust.
3. In PHP Version, choose a compatible version. If you want to return to the server default, select inherit; cPanel shows it as Inherited in the table.
4. Click Apply and wait for the success notice.

Final verification

• The domain shows the selected version in MultiPHP Manager.
• The site loads without Error 500 or blank pages.
• Your CMS admin area opens correctly.

Common errors

• The site still fails after the change → the change was applied to the wrong domain → return to MultiPHP Manager and verify the selected domain.
• A missing extension error appears → the selected version does not include what your app needs → try another compatible version.
• The site works but feels slow → the issue was not PHP version alone → review plugins, cache, and error logs.
