“Gutenberg” is a codename for a whole new paradigm in WordPress site building and publishing, that aims to revolutionize the entire publishing experience as much as Gutenberg did the printed word. Right now, the project is in the first phase of a four-phase process that will touch every piece of WordPress — Editing, Customization, Collaboration, and Multilingual — and is focused on a new editing experience, the block editor.
The block editor introduces a modular approach to pages and posts: each piece of content in the editor, from a paragraph to an image gallery to a headline, is its own block. And just like physical blocks, WordPress blocks can added, arranged, and rearranged, allowing WordPress users to create media-rich pages in a visually intuitive way — and without work-arounds like shortcodes or custom HTML. Get the best free Gutenberg themes for WordPress.
The block editor first became available in December 2018, and we’re still hard at work refining the experience, creating more and better blocks, and laying the groundwork for the next three phases of work. The Gutenberg plugin gives you the latest version of the block editor so you can join us in testing bleeding-edge features, start playing with blocks, and maybe get inspired to build your own.

serialisation problems that occur during the find/replace operation.
Mobile device compatible: All-in-One WP Migration is the first plugin to offer true mobile experience on WordPress versions 3.3 and up.
19. WP Super Cache
This plugin generates static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.
The static html files will be served to the vast majority of your users:
- Users who are not logged in.
- Users who have not left a comment on your blog.
- Or users who have not viewed a password protected post.
99% of your visitors will be served static html files. One cached file can be served thousands of times. Other visitors will be served custom cached files tailored to their visit. If they are logged in, or have left comments those details will be displayed and cached for them.
The plugin serves cached files in 3 ways (ranked by speed):
- Expert. The fastest method is by using Apache mod_rewrite (or whatever similar module your web server supports) to serve “supercached” static html files. This completely bypasses PHP and is extremely quick. If your server is hit by a deluge of traffic it is more likely to cope as the requests are “lighter”. This does require the Apache mod_rewrite module (which is probably installed if you have custom permalinks) and a modification of your .htaccess file which is risky and may take down your site if modified incorrectly.
- Simple. Supercached static files can be served by PHP and this is the recommended way of using the plugin. The plugin will serve a “supercached” file if it exists and it’s almost as fast as the mod_rewrite method. It’s easier to configure as the .htaccess file doesn’t need to be changed. You still need a custom permalink. You can keep portions of your page dynamic in this caching mode.
- WP-Cache caching. This is mainly used to cache pages for known users, URLs with parameters and feeds. Known users are logged in users, visitors who leave comments or those who should be shown custom per-user data. It’s the most flexible caching method and slightly slower. WP-Cache caching will also cache visits by unknown users if supercaching is disabled. You can have dynamic parts to your page in this mode too. This mode is always enabled but you can disable caching for known users, URLs with parameters, or feeds separately. Set the constant “DISABLE_SUPERCACHE” to 1 in your wp-config.php if you want to only use WP-Cache caching.
