Thanks, Roy - Browse item sets problem

Dear community!

I’m using Omeka S 3.1.1. I installed Thanks, Roy version 1.0.2. The problem is that the sets are not showing up in Browse item sets. When I change to the Default theme, everything is fine.

Please help

After updating to Omeka S v. 4.0.1 and Thanks, Roy v. 1.1.1, the problem has been solved.
