Error when posting a comment

Hello!

Each time when a user presses ‘Send a comment’ button, it shows a blank page with the following errors:

Warning: Invalid argument supplied for foreach() in /var/www/u1316335/data/www/u1316335.isp.regruhosting.ru/wp-content/plugins/master-addons/inc/modules/header-footer-comment/inc/comments/class-comments-builder.php on line 138

As I understand, the last two errors show up because of the first one. What I have on lines 137-151:

if(isset($comment_meta )){
                foreach ($comment_meta as $key => $value) {
                    
                    $label_name         = $value['label_name'];
                    $field_type         = $value['field_type'];
                    $required           = $value['required'];

                    $unique_field_id    = strtolower(str_replace(" ", "_",$label_name));
                    
                    $jltma_field_value = 'jltma_' . $unique_field_id;

                    if( isset( $_POST[$jltma_field_value] ) )
                        update_comment_meta( $comment_id, $jltma_field_value, esc_attr( $_POST[$jltma_field_value] ) );
                }
            }

Please, help!
