Hi, I'm trying to get the default "mystery man" avatar to display for users who don't have a Gravatar set up yet, but it's showing a broken image.
Gravatars are displaying for users who have them set up. Broken images are displaying for those who do not. Here's the image source URL for one of the broken ones (note, this looks practically identical for users who have Gravatars, just the long string of numbers is different):
And the file "mystery-man.jpg" is right where the file path suggests starting at "/wp-content..."
Since this is working for Gravatar users and not for non-Gravatar users, I'm stumped as to where to begin to debug. Any suggestions?
