This theme is WPML compatible, the plugin makes it easy to translate your website into multiple languages. The “String Translation module” is included with the “Multilingual CMS package” and will allow you to translate any strings not included inside posts, pages, or taxonomies. It’s very easy to use and is located at WPML > String Translation.
NOTE: You’ll be translating both the theme language files and my Contempo Real Estate Custom Posts plugin language files.
Below is the link to the guide on the WPML website which goes into greater detail. I would strongly recommend you check it out.
Once installed and configured the lang switcher in the header will automatically appear, based on the languages you’ve set.
