I’m also having this problem.
I’ve been in touch with Ryte over this, and they claim it has something to do with Yoast and Google having a mismatched URL name. The final slash on the end of the name (which appears in Google, but not in Yoast) is the culprit they say.
However, I am unable to find a way to change this.
Any ideas, Yoast? I’ve paid you guys quite a bit of money already for your plugin across my sites, and so far it’s been good. Don’t let me down please.
