Before you start
The domain you updated and access to its hosting settings.
A test login if the site has customer accounts.
A safe way to test orders or bookings without creating unwanted charges.
Steps
1. Check that the intended PHP version is saved in the hosting settings.
2. Open the homepage in a private browser window.
3. Visit several other pages, including a product or service page.
4. Try the menu links and site search.
5. Sign in to a test account if the site has a login.
6. Submit a contact form using an email address you can check.
7. Confirm that the form message arrives.
8. Test checkout or booking using the site’s approved test method.
9. Check any scheduled jobs or integrations the site depends on.
10. Repeat the checks for other websites affected by the PHP change.
Example
For a contact form, success means both seeing the confirmation on the website and receiving the message. A “Thank you” message alone does not confirm delivery.
Questions and troubleshooting
I see an old page. Try a private window and clear the site cache if you use one. Cache clearing can refresh content, but it does not repair PHP errors.
Only one feature fails. Record the page, action and error. That helps identify a problem with a particular plugin or part of the site.
WordPress shows a different PHP version. Check Tools → Site Health → Info → Server. If it differs from the hosting setting, send us the domain and both version readings.

Next steps
Once the checks pass, keep a note of the update date. If you pay for PHP Extended Support, check whether that service is still needed.
