To change an eligible domain's PHP version:
- Open MultiPHP Manager.
- Select the desired domain.
- Choose one of the PHP versions made available on the server.
- Apply the change.
- Test the website, forms, scheduled tasks, and administration pages.
If a site fails after the change, return to the previous known-working PHP version while you identify incompatible code. Do not assume the newest available PHP version is automatically compatible with every legacy application.
