Clear The oEmbed Cache in WordPress

How to Clear oEmbed Cache in WordPress

While publishing content on your site, you might want to embed some YouTube videos, tweets, or even Google Maps to make the article unique and helpful for your visitors. In most cases, your server will fetch the embedded content and store it as an oEmbed cache. This is not the basic WordPress caching system but like any other cache, it’s important to clear it regularly. That’s why in this guide, we are going to show you how to clear the oEmbed cache in WordPress.

What’s the oEmbed cache?

When you paste a YouTube video URL on your site or use the Gutenberg blocks, WordPress checks the destination URL and searches for the content that needs to be embedded. So, when a visitor goes to the page where you have embedded the video, your server will automatically generate cached files in your website’s database.

This process is possible thanks to the oEmbed cache. It allows a website to display any embedded content without the need to parse the source of the content.

Although you can clear your site’s cache by using any caching plugin, you won’t be able to remove the oEmbed cache just like that.

Why clear the WordPress oEmbed cache?

Your web server will store the cache for some time. But, when you need to fetch the updated content, you might want to clear your existing oEmbed cache and generate new ones.

For example, let’s say you have embedded several YouTube videos on your site. In some cases, later on, the YouTube channel owner may update the thumbnail of the video or make some changes to it. However, those changes won’t display on your site if you use the old cache.

When you embed the video for the first time, your server fetches all this information from the third-party server, caches the content, and renders it in the frontend. So, clearing the cache will help you fetch the recently updated content from the third-party server. On the other hand, if the code generated through the oEmbed is damaged and you can’t see anything in the frontend, it’s a good idea to clear the cache too.

So now that we better understand the topic, let’s see how to clear the oEmbed cache in WordPress.
