MultilingualPress

WARNING: MultilingualPress 2 is not compatible with Gutenberg. BEFORE you update your WordPress to version 5.0 please read our MultilingualPress and WordPress 5.0 guide. Exciting news! MultilingualPress 3.0 is released and available for Pro users! Fully refactored, based on PHP 7, Gutenberg support, improved UI and optimized for WooCommerce. Get it here! Please note, you can't update MLP2 to MLP3 as usual, this is a complete refactor. We are currently working on a Migration tool which is available as alpha version on github. A tutorial for the migration tool can be found here Run each language in a separate site of your WordPress multisite and connect the content in a lightweight user interface. To allow your users switch between languages, create a language switcher in your custom menu or use a customizable widget. This plugin lets you connect an unlimited amount of sites with each other. Set a main language for each site, create relationships (connections), and start writing. You get a new field now to create a linked post on all the connected sites automatically. They are accessible via the post/page editor screen - you can switch back and forth to translate them. In contrast to most other translation plugins there is no lock-in effect: When you disable our plugin, all sites will still work as separate sites without any data-loss or garbage output. Our Language Manager offers 174 languages, and you can edit them. Features

• Set up unlimited site relationships in the site manager.
• Language Manager with 174 editable languages.
• Edit all translations for a post or page from the original post editor without the need to switch sites.
• Show a list of links for all translations on each page in a flexible language switcher widget.
• Translate posts, pages and taxonomy terms like categories or tags.
• Menu language switcher: Add translation links to any nav menu.
• No lock-in: After deactivation, all sites will still work.
• SEO-friendly URLs and permalinks.
• Support for top-level domains per language (via multisite domain mapping).
• Automatic hreflang support.
• Support for custom post types.
• Automatically redirect to the user's preferred language version of a post.
• Duplicate sites. Use one site as template for new site and copy everything: Posts, attachments, settings for plugins and themes, navigation menus, categories, tags and custom taxonomies.
• Synchronized trash: move all connected post to trash with one click.
• Change relationships between translations or connect existing posts.
• Quicklinks. Add links to language alternatives to a post automatically to the post content. This is especially useful when you don't use widgets or a sidebar.
• User specific language settings for the back-end. Every user can choose a preferred language for the user interface without affecting the output of the front-end.
• Show posts with incomplete translations in a dashboard widget.

We cannot guarantee free ad hoc support. Please be patient, we are a small team. You can follow our progress and development notices on our developer blog. Premium Support We also offer premium support to save your time. You get direct help from the developers of the plugin-and support the development. WPML to MultilingualPress If you would like to switch from the WPML plugin to MultilingualPress, you can use the helping hands of WPML to MultilingualPress. This plugin converts posts from an existing WPML multilingual site via XLIFF export/import for MultilingualPress. Crafted by Inpsyde The team at Inpsyde is engineering the Web since 2006.

This is faster than the previous option call, and it is less error prone, because we don’t have to synchronize these relations between sites. The old options will be imported into the table automatically during the upgrade.
• Pro: Post meta fields in poorly written plugins will not be overwritten anymore. We had many reports about plugins without a check for the current site when they write meta fields. Now we remove all global post data before we synchronize the posts, and we restore them when we are done.
• Installation and uninstallation are heavily improved now. We catch many more edge cases and switches from Free to Pro.
• Languages are now synchronized between MultilingualPress and WordPress. When you assign a language in MultilingualPress to a site the first time and the language files are available, we set the site language in the WordPress option to that value.
• You can add language links to regular navigation menus in the backend now. These links are adjusted automatically on each site: if there is a dedicated translation, the link will be changed to that page. It will point to the other site’s front page otherwise.
• Users who are not logged in will not get permalinks for non-public sites anymore. You can work on a new site now safely, test all the links while being logged in, and your visitors will never see that until you set the site to public.
• You can link existing terms (tags, categories, whatever) now. We will add support for term creation on that page later.
• There are hundreds of other, minor improvements, too many to list them all.
