This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



This plugin creates a dynamic HTML5 application cache manifest for each site and blogpost of your wordpress blog.

Features so far:
– Sidebar-Widgets, Sites and Posts are cached. – The Index Site of your Blog gets fully cached. – Support for the Advanced Customfields Plugin (only tested w/ standard version + repeater plugin) – On “Save post” event a new Appcache manifest will be generated (so the clients will update the content)

What this plugin can not do: – Cache youtube videos. – fix dead links


  • Settings for the application-cache-plugin. The current theme folder gets cached by default. You can alse exclude filetypes (default is .less .sass)
  • Appcache-plugin in action (See the events "Application Cache Caced event")


  1. Upload the appcache/ folder to your /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Place manifest="<?php echo site_url(); ?>/wp-content/plugins/appcache/manifest.appcache.php?appcache_id=<?php echo the_ID()."&referrer=".urlencode($_SERVER['SCRIPT_URL']); ?>" in your header.php INSIDE the html tag. It should look like this: <html manifest="...php stuff...">
  4. test it (look below in the FAQ)
  5. Thats it, but feel free to look at settings -> appcache in your admin interface. There are a few settings you can do


How to Debug / look at the appcache / Is it working?

Its easy in Google Chrome:
– Debug by CMD+ALT+J for Javascript console.
– You can see the events fired up by the appcache manifest. Read them carefully! – If you get a HTTP 404 on any link to a img: the site wont get cached.
– type chrome://appcache-internals/ in your addressbar to look at all HTML5-Cached Sites. – If nothing is there be sure to look at the manifest. If any error is thrown there please send me an email with a link to the manifest.
