WordPress themes control the look and feel of your WordPress blog, from the layout and graphics to the colors of text and links.
After updating the theme to the next version, if you see the broken website or feel that the changes are not reflected on the website, then please clear all cache memories. Your web browser, hosting server, and caching plugins can all serve cached content which can make it difficult for you to see the changes you made to your website right away. Clearing your WordPress cache is also the first troubleshooting step that needs to be performed.
In this article, we will show you how to properly clear the cache in WordPress.
Clear Your Browser Cache
Most web browsers store static content like stylesheets, JavaScript, images from a website to make your subsequent visits faster. When you update the theme, image, stylesheets, and JavaScript files changes. But if your browser has cached the website content, it will serve the old cached files even if they have been updated. To see all the changes, you need to clear all the old files stored in the cache memory and refresh your browser to load the updated files.
To clear browser cache in Google Chrome, first, you need to click on the menu icon on the top-right corner of the screen (three dots) and then select More Tools » Clear Browsing Data. After clearing the cache refresh the browser content.
To clear browser cache in Firefox, you need to click on the hamburger menu on the top-right corner of the screen and select the ‘Preferences’ option. This will bring up the Firefox settings page. From here, you need to switch to the ‘Privacy and Security’ tab, and then click on the ‘Clear Data’ button.
To clear browser cache in Safari, click on the History » Clear History… option from the top menu.
Clear Cache in Your WordPress Caching Plugin
If you are using a WordPress caching plugin on your site, you need to clear your plugin cache. Most caching plugins allow you to easily do that from the plugin’s Settings page. Go to the settings page of your plugin and click on the option to clear/delete the cache memory.
Clear Cache of Hosting Server
Some hosting provider like Bluehost/WP Engine run their own caching solution, so their customers don’t need to install a caching plugin.
After theme update, If you are unable to notice the changes take effect immediately, then you can easily clear the hosting server cache from your WordPress admin area.
Simply log in to your WordPress admin area and you will notice a ‘Caching’ button in the admin tool bar. Click on the option to ‘Purge All’ cache.
