HOW-TO: Manually set the PHP version associated with your domain and subdomains

In Davidson Domains, each domain and subdomain may have its own associated version of PHP. This allows flexibility in running software, themes, plug-ins, etc. that may have compatibility problems with the latest version of PHP. Set the PHP version using the steps below.

A note about defaults and minimums: By default, all new domains and subdomains are set to Inherit the system PHP version — that is, to take the same setting as the system default. As of 29 February 2023, that will be version 8.0, and version 7.4 will be the minimum version available. Versions 7.2 and 7.3 will no longer be available, and any domains/subdomains still using 7.2 or 7.3 will be automatically updated to version 8.0. Domains set manually to use version 7.4 (rather than to Inherit) will retain that setting.

T&I strongly recommends that you test your software, themes, plug-ins, etc. with the latest versions of PHP (8.0 and 8.1), and manually update your PHP settings ahead of the February 29 change. Any software found to be incompatible with PHP 8.0 should be either updated, or its use be discontinued.

  1. Log in to Davidson Domains as usual, and open your Dashboard. Locate the Software section, and click the icon for MultiPHP Manager.
  2. In the MultiPHP Manager window, move down the section labeled Set PHP Version per Domain. From the list of domains, check the boxes for the ones you want to modify PHP for. Note that any listings bearing the Inherited flag are using the default system version of PHP.
  3. From the PHP Version menu, select the version of PHP you want associated with the selected domain(s). Click Apply.
  4. When the change executes, look for a success notification similar to the one shown below.
  5. Notice that the PHP version indicated in the domains list now reflects your chosen setting, and the Inherited flag is gone, indicating that you set this version manually.
