First, apologies for answering so late. I largely rely on the RSS feed of the forum to know when someone posted a feature request, and www.remarpro.com changed the link to this feed AGAIN! ??
As for your problem: It’s hard to tell without further information. “not showing” can mean a lot of things. Are you getting a 404 error for the image? Are other gravatar images displayed normally? Is the default avatar displayed when you change to one of the default “default avatar” images? It might also help to know your PHP and WordPress versions.
If this problem still exists for you, can you point me at a URL where I can see the missing image? If you don’t want to post the URL here, drop me a line via https://code.freudendahl.net/kontakt/
