Screenshot from https://grandperspectiv.sourceforge.net which you can also get from the App Store to support the development of the utility!

Wow, that's all taken up by the dynamic wallpaper videos 😅

Here is an interesting playground plugin for anyone running WP multisite https://wordpress.org/plugins/multisyde/

1. Centralized plugin activation/deactivation without going to each site.

2. Show the timestamp of the last login for each user on the network.

Is there a WordPress plugin that shows a confirmation prompt when updating a published post?

Attached is what I had in mind based on the dialog used by the full side editor when making site-wide changes.

New video: Pealing the four layers 🧅 of WordPress caching:

🌍 Runtime object cache stores data just for the current request.

🪨 Persistent object cache shares cached results across requests.

🗂️ Advanced cache serves full HTML via PHP.

🚀 Full-page cache skips WordPress entirely.

My latest guide on WordPress emails explains how it all works:

✅ How wp_mail() really works
✅ Setting headers, SMTP, and DKIM correctly
✅ Using filters like phpmailer_init to lock it all in

👉 Read the guide: https://wpelevator.com/guides/wordpress-emails/

Most WordPress sites are failing silently at email delivery.

Emails sent by wp_mail() get flagged, dropped, or bounced, and most devs never notice until it breaks something critical.

❌ Password reset links that go to the wrong site
❌ SPF and DMARC misalignment
❌ Invalid Return-Path headers

For context: https://github.com/sebastianbergmann/phpunit/issues/4621 and https://github.com/sebastianbergmann/phpunit/issues/5878

TIL: PHPUnit no longer supports test filenames being different from the test class names (i.e. `class-` prefix used by WP) since version 9.

Why enforce this? I assume reflection is still used for resolving the actual class names so there is no practical need for them to match.

Created a single markdown file (6.5MB) with all of WordPress developer handbooks which you can add to your project for AI context.

Interestingly, AI can also help identify gaps in the documentation and provide some really insightful tips for improving it.

As part of the Modern WordPress Fast Track course launch, I’m sending out weekly tips and tricks to all subscribers of our FREE newsletter.

We’re kicking things off with a fun little journey through the quirky, chaotic, and clever history of web browsers — from the early days of WorldWideWeb (the actual name of the first web browser) to the performance-focused powerhouses we use today like Chrome and Firefox.

Did you know that web browsers used to include authoring tools for creating websites? A true WYSIWYG experience before even FrontPage and Dreamweaver existed.

Now we can’t even view source on mobile 😅

Luckily we still have very powerful developer tools bundled with the browsers — from inspector (remember Firebug?) to network monitoring and even performance analysis.

Should MCP servers have access to system shell? 🤔

Here is a bare-bones MCP server written in PHP being used in VS Code over SSE to get DNS records using dig.
