  		$wpml_current_language = strtolower( $lang );
  		echo wpautop( wp_kses_post( apply_filters( 'wpml_translate_single_string', get_option( 'ivole_email_body', $def_body ), 'ivole', 'ivole_email_body', $wpml_current_language ) ) );
  

• With:

  	//WPML and Polylang integration
  	if ( has_filter( 'wpml_translate_single_string' ) && defined( 'ICL_LANGUAGE_CODE' ) && ICL_LANGUAGE_CODE && !function_exists( 'pll_current_language' ) && $ivole_language === 'WPML' ) {
  		global $sitepress;
  		$wpmllangs = $sitepress->get_active_languages();
  		if (ctype_upper($lang) && (ctype_upper($wpmllangs[$lang]["code"]))){
  			$wpml_current_language = ( $lang );
  	} else {
  			$wpml_current_language = strtolower( $lang );
  		}
