I) Using SSH
Sometimes when you log in to your WordPress site you may see a message saying;
"No Update Required Your WordPress database is already up-to-date!"
Many times this issue occurs due to your site's cache. To resolve this issue you have to log into your server and flush the cache via SSH. The steps to flush caches are given below:
1. First, log into your server using SSH(Secure Shell).
2. Then go to your WordPress directory.
3. In this directory, run the command given below:
[server]$ wp cache flush
After this, the issue will be fixed and you will not get the message again.
II) Using a Plugin
1. Install any Cache clearing plugin. In our example, we are going to use the WP Rocket plugin.
2. After installing the plugin go to Settings> WP Rocket.
3. In the WP rocket, the plugin dashboard clicks on the CLEAR CACHE button. With this, all the cache will be cleared.
III) Using the Server/Hosting
You can also clear cache using the server of your site.
1. First login to the cPanel of your WordPress site.
2. Then go to the Cache Manager option present in the ADVANCED section. Note that all hosting providers do not provide this option.
3. After entering the page clear all the website cache. After this, the issue will be fixed.
