The '429 Too Many Requests' error in WordPress usually happens when a user, bot, or script tries to make a lot of requests to your website in a short period. This is like a protective measure to stop potential attacks on your site, known as DDOS attacks.
Imagine your website as a busy doorway. To keep things running smoothly, there's a limit on how many people can enter at once.
If too many try to get in at the same time, the door says "hold on" to some of them, and that's when you see the '429 Too Many Requests' error.
One scenario where you might encounter this error is when there are too many requests from your WordPress website.
If a plugin or a piece of code is trying to load too much information too quickly, your website's security might say, "Wait, that's too fast!"
This can affect how your site shows up in search engines and may even prevent you from logging in to your WordPress admin dashboard.
Sometimes, your site might be asking another website for information using something called an API (like a messenger between websites).
If your site asks too often or too quickly, the other website might say, "Hold on, you're asking for too much too soon," and it responds with a '429' error.
That being said, let's look at how to easily troubleshoot and fix the '429 Too Many Requests' error in WordPress.
