404 Error when I try to clear Gravatar cache
Some of the users who leave a comment are displaying the default gravatar image https://d.pr/i/gyzcOE and I'm not sure why. I have a custom Gravatar set for commenters on my site, you can see it above and below the default gravatar icon in the image above.
I tried clearing my gravatar cache in the wpdiscuz settings but when I do I get a 404 error message.
Please disable other plugins and check it. Also please disable wpDiscuz and check it. Make sure this is a wpDiscuz specific issue.
Also please navigate to Dashboard > Settings > Discussions admin page and check WordPress native avatar settings, leave a screenshot of the avatars options, I want to see which one is selected.
Also please try to disable wpDiscuz Avatar cache.
