In order to create a Multilingual Site,  you have to use a translation plugin. Multilingual plugins offer WordPress users the ability to run a multilingual site with a single WP install.


The multilingual WP plugins are free and premium (paid). The most popular premium plugin is WPML.


WPML ( Tested with all VamTam themes)


WPML is a premium multilingual plugin, designed to make it easy to build and run multilingual sites and blogs, and translate pages, posts, and other content. The default install offers more than 40 languages, and users can arrange different language content in the same domain via language directories, in sub-domains, or in completely different domains.


One of the other cool features of WPML is the ability to translate comments, so when international visitors comment in languages you don’t speak, you can read them and reply. As a premium plugin, the cost runs between $29 for blogs, and $79 for websites.

FREE Alternative to WPML


Polylang



Polylang is another free plugin via the WordPress Plugin Directory, adding multilingual content management support to standalone WordPress sites. WordPress language files are automatically downloaded and updated, so you can translate posts, pages, media, categories, post tags, menus widgets and more.


Polylang has been downloaded more than 117,000 times, and has an average user rating of 4.9/5 stars.


Polylang is a bit younger than qTranslate, but is coming along quite nicely. It creates entirely different posts for each defined language, which makes everything a bit cleaner. However, it has a bit of a steep learning curve, as it doesn't come with an installation wizard that lets you set up everything right from the start.
