Hi Long,
All that I understand. But for doing so, I don't need to install & activate the MB User Avatar plugin. Actually, that plugin results in another field in the user profile than the created custom field. So with the plugin active I have 2 profile image fields.
I am puzzled about the so called solution of the MB User Avatar. It seems not to be used at all.
Or am I missing something?
Then back to how to get it working. I think I have done all what's in the documentation (deactivated actually the Avatar plugin), but the WordPress Profile picture is not changing. I guess that's what you mean with "single_image with code", is that the code in the functions.php file?
Can you help me with the code that needs to be changed?
