Moving your WordPress site off PHP 8.2?

See which plugins need attention.

A pass/warn/fail table for every plugin and theme on PHP 8.3 and 8.4, with file, line and whether each issue is auto-fixable or manual.

Get diffs your developer can apply.

Standard and Premium include patch diffs for auto-fixable issues in your custom code and a re-check log on the patched copy.

Keep your site access to yourself.

You send a zip of plugin and theme folders you download yourself. We never ask for passwords, admin access, FTP, SSH or database dumps, and we never execute your code.

Free checklist: before you leave PHP 8.2

  1. Find your current PHP version: Tools › Site Health › Info › Server.
  2. Read your host's notice: when will they move PHP 8.2 sites, and to which version?
  3. List your plugins and themes, and mark which ones are custom code.
  4. Update plugins, themes and WordPress core to their latest versions first.
  5. Check each plugin's page or changelog for PHP 8.3 or 8.4 support.
  6. Make a full backup and a staging copy of the site.
  7. Switch only the staging copy to PHP 8.3 or 8.4 in your hosting panel.
  8. Turn on the debug log on staging and test the pages that earn money: cart and order pages, payments, forms, emails, admin.
  9. Fix or replace anything that shows errors or deprecation notices, then test again.
  10. Switch the live site at a quiet time, with a rollback plan ready.

Prefer to hand over steps 3, 5 and 9? That is what the paid check covers. See the full guide

Not included: changing your server's PHP version, uploading or deploying files, work that needs access to your site, running your code, database work.

Static checks cannot see every runtime problem, so test on staging before you switch the live site.

No access to your site, ever

We work only from a zip of plugin and theme folders that you download yourself. Please leave out wp-config.php, .env files and database exports. If you send access details by mistake, we will not use them and we will ask you to change them.

FAQ

What happens on 31 December 2026?

The PHP project stops releasing security fixes for PHP 8.2 (source: php.net). Your site does not switch off that day. Hosts move customers to newer PHP versions on their own schedules, so check your host's notice.

Do you need access to my WordPress site or hosting?

No. We never ask for passwords, admin access, FTP, SSH or database dumps. If you send access details by mistake, we will not use them and we will ask you to change them.

What do I send to get a quote?

Only your site URL and roughly how many plugins and themes it uses. Please do not attach files yet.

What do I send after I accept the quote?

A zip of the plugin and theme folders you want checked, downloaded yourself, your current PHP version, and which folders are custom code.

How do I pay?

We reply by email with a fixed quote and how to pay. Nothing is charged until you accept, and work starts after payment.

Will you switch my server to PHP 8.3 or 8.4?

No. Changing the PHP version, uploading and deploying are outside the scope. Premium includes a host upgrade checklist (staging, backup, rollback).

Can a static check find every problem?

No. We never execute your code, so problems that only appear at runtime are outside this check. That is why the checklist ends with testing on staging.

What about plugins I bought from a marketplace?

They are included in the table. For third-party code the advice is to update or ask the vendor; we make diffs only for code you mark as custom.

Can you check many sites for an agency?

Yes. Email the number of sites. Plugins and themes that are identical across sites are checked once, and you get a table per site plus one summary.

What happens to my files?

We use them only for your order and delete them 14 days after delivery.
