OK – first I feel like an idiot, as it was that my function(s).php was missing the the s. Hate those minor errors. I always forget to check the simplest thing first. Thank you!
Now, the filter is working. However, I am encountering another problem. It has to do with linking. With the filter on, the URL to the item: /company/companyName/ and when you view the item, the page comes up 404. But it will come up at the OLD url listed /organizer/companyName
add_filter('tribe_organizer_label_singular', 'change_single_organizer_label' );
function change_single_organizer_label() {
return 'Company';
}
add_filter('tribe_organizer_label_plural', 'change_plural_organizer_label' );
function change_plural_organizer_label() {
return 'Companies';
}
The issue becomes, any link to the organizer page, does not work.
