Hi @rsalafy,

Those warnings indicate that the issue is originating from one of your active code snippets during execution.

If you can share the snippet, we can help identify the problem and suggest a solution.

Thanks,

I got no error messages when I first created the snippet weeks ago, only recently.

HI @rsalafy,

The errors were caused because the code snippet was trying to access the $post variable, which isn’t always available on every page or in every context of WordPress. When $post isn’t set, trying to use $post->ID results in warnings (like “Undefined variable” or “Attempt to read property ‘ID’ on null”).

We suggest adding code to check if a post is actually available before using it.

Here is the modified code snippet:

global $post;

if ( isset( $post ) && is_object( $post ) ) {
    if ( function_exists('yoast_breadcrumb') ) {
      yoast_breadcrumb( '<p id="breadcrumbs">','</p>' );
    }

    echo '<table>';
    the_terms( $post->ID, 'shipment-service', '<tr><th>Shipment Service</th><td>', ', ', '</td></tr>' );
    the_terms( $post->ID, 'shipment-status', '<tr><th>Shipment Status</th><td>', ', ', '</td></tr>' );
    the_terms( $post->ID, 'delivered-in', '<tr><th>Delivered in</th><td>', ', ', '</td></tr>' );
    the_terms( $post->ID, 'package-weight', '<tr><th>Package Weight</th><td>', ', ', '</td></tr>' );
    the_terms( $post->ID, 'amount', '<tr><th>Amount</th><td>', ', ', '</td></tr>' );
    echo '</table>';
}
