GPT-4 provided the following patch suggestion:

<?php
// wp-content/plugins/listdom/app/includes/menus/ix.php

// Locate the line that contains the following code:
trim( $value );

// Replace it with the following code:
if ( is_string( $value ) ) {
$value = trim( $value );
} else {
$value = '';
}

// Save the modified file and upload it to the appropriate location on your WordPress installation.
