Hey @Mad Dog,
I’m sorry that you’re having trouble with your customizations! Before we get started, I would like to highlight that we cannot offer any support for custom code.
With that being said, in general one thing that is not helping your code along is that the function tribe_get_custom_field(), singular, is these days a deprecated function.
So your best option would be to use the annoyingly-similar plural version of this function: tribe_get_custom_fields()
Here’s a rough version of your original code rewritten to use this function, which may not fix your problems outright, but is an essential step before any others:
$fields = tribe_get_custom_fields( $event->ID );
if ( isset( $fields['Instructor'] ) ) {
echo 'Instructor: ' . $fields['Instructor'];
}
I hope this helps!
