 * Thanks for the info. Does it work if you just replace
 * `$polylang->model->get_post_language`
 * with
 * `PLL()->model->post->get_language`
 * ?

 * Hey Mikko,
    I tested to switch “$polylang->model->get_post_language” to “PLL()-
   >model->post->get_language” on line 27 in relevanssi/lib/common.php and the notice
   from the debugger disapered. Thanks!

 * Hey, Mikko, having same issue. Is there a quick work around (besides changing/
   lib/common.php)?

 * This is already fixed in the current version, so the quick workaround would be
   to updating to latest version.

 * Hey, thanks for getting back. Still getting the error even on latest version 
   of Relevanssi:

 * You’re running Relevanssi 3.5.3? The line 26 of common.php in 3.5.3 is
 * `if (PLL()->model->get_post_language($hit->ID)->slug == ICL_LANGUAGE_CODE) {`
 * so I can’t see where the `$polylang->model->get_post_language()` is on that line…

 * Hm, I’m using composer to manage plugins, it (([https://wpackagist.org/search?q=relevanssi&type=any&search=](https://wpackagist.org/search?q=relevanssi&type=any&search=))
   actually shows 3.5.4 as latest and 3.5.3 on WordPress plugins directory.

 * Line 26:
    `if (PLL()->model->get_post_language($hit->ID)->slug == ICL_LANGUAGE_CODE){`
   but error still says the same. Any guesses why it is so?

 * No idea. For starters you could start a new thread for this, as this thread is
   already marked resolved.
