Sorry, I thought I replied a few days ago. But yeah, it seems to be working fine on my end. I’ve never heard of something like this happening before. There’s nothing within the theme that would prevent the plugin from working. Even the Genesis Framework shouldn’t have an effect since it automatically turns off when Yoast is activated.
I’d recommend contacting Yoast Support to see if they know what’s going on. Since it’s their plugin they’ll be able to provide a better solution if there’s an issue.
