Nirvana has always been compatible with qTranslate X. For the Presentation Page texts you can use its short tags feature.
Support for Polylang / WPML has been added since version 1.1.0. Presentation Page’s texts can be translated via the plugins’ Strings feature. With WPML, you can use the WPML Widgets plugin to easily translate the theme’s columns widgets.
If you’ve used Nirvana with other multilanguage plugins and it works, let us know so we add them to the list. If they didn’t work, let us know so we test things out and look for a solution.
