Hi immergente,
the plugin has not been tested for compatibility with the WPML. However, some users have definitely used it with WPML. You may try the basic version of our plugin with the WPML if you have it.
If you don’t have the WPML yet, our plugin already offers a large amount of translations (Brazilian Portuguese, Bulagarian, Canadian French, Dutch, Greek, Italian, Lithuanian, Russian, Spanish and Turkish)!
If the language you wish to translate our plugin into is not within the list, you can easily make your own translation. A template .POT file is given to you. You simply have to open the file with PoEdit and make your translations and upload them to your WordPress.
Regards,
