Hello, i'm getting this error on PHP log: PHP Warning: Invalid argument supplied for foreach() in /wp-content/plugins/seo-by-rank-math/includes/class-replace-vars.php on line 876 This is what that line says: // Custom Fields. $json = array(); $custom_fields = get_post_custom( $post->ID ); 876 foreach ( $custom_fields as $custom_field_name => $custom_field ) { if ( substr( $custom_field_name, 0, 1 ) === '_' ) { continue; } $json[ $custom_field_name ] = $custom_field[0]; } Helper::add_json( 'customFields', $json ); } PHP version is 7.2 How to fix it?
