If you have a WordPress site that was built before August 2020 (when WordPress 5.5 decided to stop supporting jQuery Migrate), or if you manage a site that recently weaned off jQuery Migrate, you might run into errors where the parts of your site that run on Javascript stop working.

When you open the Developer tools of your browser (that’s the F12 key for most browsers), you might also see an error message that looks something like this.

What should you do if XAMPP’s Apache service does not run on your Windows machine? Read on to find out.

Update 6 April 2023: Added some new solutions to the article.

Of all the CSS attributes that are available to web developes, the vertical-align attribute is perhaps the most mystifying. At first glance, the attribute seems like the vertical aligning cousin of the text-align attribute, but when you try and use it to vertically-centre your elements, it doesn’t work!

<div style="height:100px;background-color:#eee;">
	<p style="background:#dcc;">Item to be vertically-centred</p>

XAMPP is a great tool for web developers who need to run or test web applications locally on their own computer. Unfortunately, because it runs applications on the LAMP stack, conflicts can happen, causing certain applications on XAMPP to be unable to run.

In this article, we will be exploring what you can do if XAMPP’s MySQL service does not run on a macOS platform.

Are you looking at getting XAMPP MySQL to work on Windows instead? I’ve also wrote a guide for getting XAMPP Apache working on macOS. Do click on these aforementioned links if they are what you need instead.

If you’re running a Bitnami LAMP stack for your web server, you will be glad to find that it comes with phpMyAdmin — an indispensible tool for managing your server’s SQL server.
