Reply To: no title in content-single-reply.php
I think we’re going round in circles.
“The topic “title” is showing, it is “support”
The topic title shows above the breadcrumb, and yours resolves as
On my site this title is the topic (entry) title. so for example my site at the same point as your support title shows
<h1 class=”entry-title”>Feeding Oats.</h1>
where the topic is “Feeding Oats”
Have you amended loop-single-reply?
