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
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.

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.

Here is the relevant issue for adding this to the HTML spec https://github.com/whatwg/html/issues/6636 and a guide from Google on how to implement now https://web.dev/articles/lazy-loading-video
TIL: HTML video poster images in <video post="image.jpg"> are not lazy-loaded. You need to do the same data-poster swap trick 🪄
Here is PHP running an MCP server over SSE (not stdio) in roughly 70 lines of code 🏃♂️➡️ You don't need any of those JS libraries to use this.
There are so many undocumented features of how MCP clients actually utilize SSE. For example, the initial "endpoint" event to establish the POST request path for the actual messages.
Works great in both VSCode and Cursor!

These $200 mini PCs are perfect for weekend homelabbers:
🧠 Intel N100
💾 16GB RAM
⚡ 500GB SSD
They’ll run a full Docker stack — media center, Home Assistant, dashboards, and more with (almost) zero noise or power draw drama.
WordPress could become the CMS for MCPs 💡 with support for paid endpoints using existing ecommerce infrastructure 🤔
