Co-Authors in Avada theme

I love the idea of this plug-in! Just need to get it to work.

Using the Avada theme, backend is looking good, front-end not so much. No surprise there. I looked at the “Incorporate Co-Authors Plus template tags into your theme” article but not having luck locating the right areas in the .php files to make the changes.

I’ve contacted Avada for assistance but they have not been helpful. I admit, I am a bit of a novice at this, so I want to make sure that I do this correctly without breaking the site. Any assistance with this would be most appreciated! Thanks. ??
