It's that, I don't know why, because before I didn't have this problem, but WPForo tries to take the avatar from Gravatar, and I use personal avatar.

The problem is now resolved.

Thanks!

I see Gravatar avatars are not loaded on your forum. This problem doesn't origin from wpForo. Here are the possible reasons:

Avatars Disabled in Settings: If avatars are disabled under Dashboard > Settings > Discussion in the WordPress admin, Gravatar images will not be displayed regardless of profile setup.

Gravatar Service Issues: Gravatar.com itself may experience downtime or have CDN connectivity issues that prevent images from loading.

Lazy Loading & Custom Image Handling: Some performance optimizations (like lazy loading) or custom HTML/image rendering may inadvertently interfere with avatar display logic. This is a theme or other plugin conflicting result.

Content-Security-Policy or Network Blocking: Hosting environment, browser extensions, or security plugins might block requests to gravatar.com, causing images to be replaced by placeholders for privacy or network reasons.

If you cannot find and fix the gravatar problem we recommend set a default avatar in Dashboard > Settings > Discussion. Do not forget delete all caches before checking the result. This problem makers could be the cache/security plugins as well.

I just discovered a problem on the home page and can't find answers to my questions on Google.

I have some strange code on the home page that should display avatars, but instead I get this (see screenshot).

If anyone can help me solve this problem, thank you.
