Update Page Cache flushes and generates again the page cache. The actual version supports W3 Total Cache, WP Fastest Cache, WP Super Cache, and WP Optimize. When you modify a page and save it, usually caching plugins automatically clear the cache of that page, but you need to visit again the page to generate again the cache. Update Page Cache adds a button on every single page, post and custom post type that you can click to automatically clear and regenerate the cache of that page. Be careful, you will not see the button if you have Fullscreen mode active. When you edit a single page, if you click on the “Update Page Cache” button, the cache of that page will be automatically updated without the need to visit that page. In the main settings you can set for each post types if the plugin should automatically clear the page cache when that single post type is saved. You can also decide which page caches should be updated after saving a specific post type. In the example shown in the screenshot of the main settings, when a single blog post is saved Update Page Cache updates the cache of the blog page and homepage. When a contact form is saved, Update Page Cache updates the cache of the page Contact.
