Gravatars don't change after changing author

Can you share the code you’re using to display the Gravatar?

The site in question is https://www.comicmix.com, using Easel theme. Do you need more info than that?

Yeah… ??

Can you point out a specific post where you’ve changed the post author and the avatar remains the same? Are you using the guest authors feature by chance?

Not using guest authors– in fact, not using the plugin at the moment, as I had to disable it because of the problem, then had to go in and re-change all the authors affected. If you want to set a time, I can activate the plug-in and we can go through it via Skype or some such.

Odd that you’d experience the problem right out of the box. Just to confirm: you’ve added the necessary template tags to your theme?
