Hi, Ben. Thanks for your reply.
Yes, I can insert a line break that works, but the characters “<br/>,” while invisible in the page or post title, appear in the breadcrumb trail, so that the breadcrumb trail looks like this:
Home > Come Thou Fount<br/> of Every Blessing
I’m running WordPress 4.8, and I tried deactivating plug-ins, as you suggested.
I don’t necessarily have to have the breadcrumb trail, but I actually like the way it looks. And it gives folks another means of navigation.
