Understanding the Inherit PHP setting in cPanel

Record the current explicit version, document root and PHP-FPM status. Check the application’s compatibility before allowing a future server-default change to affect it. Ask support if you need a stable explicit runtime.

1. Open MultiPHP Manager and inspect the domain’s current setting and PHP-FPM indicator.
2. If inheritance is appropriate and permitted, select the domain, choose inherit and apply the change. Do not disable PHP-FPM blindly just to make the option available.
3. Understand the effective lookup: applicable PHP information in .htaccess along the directory hierarchy can influence the result before the server default is used.
4. Check the application’s actual runtime after the change and test its important workflows.
5. If the resulting version is unsuitable, select an explicit supported version through the panel and retest. Keep the domain’s runtime choice documented for future migrations.

The displayed configuration and effective web runtime should agree with the intended policy. Check nested document roots carefully because another domain’s configuration can affect inheritance.

If a domain is set to Inherit, its effective version depends on the server or parent configuration that applies to it. Record both the selected mode and the version the website actually runs. The word Inherit is not itself a PHP version.

Compare the domain's document root and handler settings with the intended service configuration. A different domain, subdirectory or scheduled command may use another runtime. Check the application requirements before deciding whether an explicit version is more appropriate.

How should I make the change safely?

Preserve the current setting and test on a staging copy where possible. After selecting the intended version, exercise the application's important functions and inspect errors. Include uploads, database operations and scheduled work, not only the public home page.

If the selected version is unavailable or the effective runtime still differs, contact us with the domain, document root, selected mode and observed version. Do not publish a permanent diagnostic page or send an unredacted environment dump. We can help determine which supported configuration controls the request without asking you to edit server-wide files from a shared-hosting account.

If inherit cannot be selected with PHP-FPM active, that is a supported limitation rather than an error to bypass. Do not paste copied handler blocks into every folder. Have support review conflicting generated configuration and use the panel’s supported runtime controls.
