Not Enough Arguments?

Hi! Big fan of your themes! Recently I started translating my site with Polylang. At first I used Fluida, however, I found the post on the Fluida forum that stated I should switch to Kahuna for the time being, and so I did. I started translating my Posts. And I noticed there was an error in the header breadcrumbs stating : WARNING: SPRINTF(): TOO FEW ARGUMENTS IN /HOME/**mysite**/PUBLIC_HTML/WP-CONTENT/THEMES/KAHUNA/CRYOUT/PROTOTYPES.PHP ON LINE 764

I have no knowledge of coding or so whatsoever concerning PHP, so I don’t know what that means.

Also, when I activate Polylang, on the translated version, the menu stops working, as in, the dropdown feature stops working. I had the same problem on Fluida and I don’t know how to fix it.

I have posted the website URL so you can see the error and the menu.

Thanks in advance!
