Thank you for your reply.
I already contacted the developer of the theme who informed me that the problem was not with the theme but with gravatar. The supportpage of Gravatar informed me to ask my question here.

I will contact the developer again and ask him to look for the problem again.

Thanks for your help.

Yes. When switching to the Twenty Fifteen theme, the Gravatars display again.

Thank you for your quick answer.

I realize now that I was looking at the Demo of the premium version of Luminescence thinking it was the Lite version.

What was the problematic code exactly? I am having the same problem, but can’t find the problem exactly.
