Thanks so much for your speedy reply!
I played around with the other plugins I’m running to see if they are interfering with AIOWP. And it looks like one of them was. I’ve deleted it since it was pretty much obsolete and now the link on the infringing site is broken and returns a 403 error.
I’m assuming that’s what it’s supposed to do, return a 403 error. Is that correct?
Thanks ??
