replace (comment) this line in wp-content/plugins/polylang/frontend/choose-lang.php file (line 185)

$language = $this->options['hide_default'] && ( ( isset( $_SERVER['HTTP_REFERER'] ) && in_array( parse_url( $_SERVER['HTTP_REFERER'], PHP_URL_HOST ), $this->links_model->get_hosts() ) ) || ! $this->options['browser'] ) ?
        $this->model->get_language( $this->options['default_lang'] ) :
        $this->get_preferred_language();  // sets the language according to browser preference or default language

$language = 'fa';
