Resolved.

It works! Thank you so much! I would have never figured that out on my own. Just needed to switch out that first line in my response above with this:
if ( ! in_array ($category->name, $uniques) ) {

Works beautifully. I don’t understand how it works really, but very thankful.
Guess I need to spend some time wrapping my head around loops some more.

Have a good week

Thanks for the reply!! Looks like a smart approach. So there were some errors:
Says that the ‘$category->name’ portion of line:
if ( ! in_array ($uniques, $category->name) ) {
as well as the ‘$unique’ portion of line:
if (in_array ($categories [0]->name, $unique)) {
are strings when they should be arrays? So I changed $unique to $uniques in the second line, and that got rid of that error. Now trying to figure out the other error, from that first line.

Any ideas?

Thanks Pablo. So for the URL portion of ajax, I’d use: https://www.website.com/wp-admin/admin-ajax.php ?

Yes, as i said I did change the link in Settings. But after doing so, the error message came back so I reverted back to http. For some reason, having all pages set to https made the error message come back. Very strange.

Thank you for the plugin link. I will try that although I do not expect it to solve the problem. It seems that something subtle has changed because despite reversing all changes I had made, the error message does not disappear whereas, previously, it did disappear.

Any ideas as to what could have changed? Thank you.
