I still remember the first time I crashed my own website.
I was following a tutorial that told me to paste a code snippet into my functions.php file, and I must have missed a single character. I saved my code, and my entire site disappeared.
I couldn’t even log into the WordPress dashboard to undo my mistake!
It took me hours to get everything back online, and the whole thing was incredibly stressful.
That experience changed how I work with WordPress. Today, I never edit theme files directly, so in this post I’m going to walk you through my process.
This approach includes built-in checks that prevent a typo from taking your site offline. Quite simply, it’s the only way I recommend adding custom code to your WordPress.
