 * Hi there,
 * The free version does not support Polylang yet.
 * Polylang has a WPML compatibility feature for themes or plugins that have been
   written to play nicely with it. The free version of the plugin uses deprecated
   WPML action hooks and filters.
 * Note the premium version of the plugin supports Polylang, and is certified WPML
   compatible too!
 * Thanks,
    Daniel

 * I’m using the PRO version of the plugin v.5.3.1, I have already reviews and everything
   works fine but right after the install of Polylang Pro, the entries of a CPT 
   loose the associate ‘post-title’ in the backend table entries.
    In the database
   I still see the right post_id. Obviously, placing new review and approve others
   ecc.. won’t work!! what could be the problem? Thanks in advance!
