Issue for changing Mystery Man avatar

Try the following:

add_filter( 'pre_option_avatar_default', function( $value ) {
	return 'https://path/to/default.png';
} );

Hi Konstantion,
Unfortunately, the issue stays exactly the same…

Actually, the return url is not exactly the same…

https://1.gravatar.com/avatar/1d2ab164559aaf8a30eebf516d2f63ad?s=80&d=http%3A%2F%2F((mysite))%2Fwp-content%2Fthemes%2Frttw_v2%2Fimg%2Favatar.jpg%3Fs%3D80&r=G

Looks like your theme is overwriting it. Does it also not work on a different theme?

So, I tried on Twenty Fifteen but it did not work neither.

Do you know where may I check for the overwriting ? Right now, I just call

<?php echo get_avatar( $comment, 80 ); ?>

On my functions.php file to get a custom template based on wp_list_comments().

Could be in a theme or plugin. I tested the code on my local install and it worked. Where are you inserting it?

I have tried at the top and at bottom on function.php of my custom theme and Twenty Fifteen.

I will try to turn off all plugins and I let you know.

Ok, so I have tried without plugins on a local and live intalls but both did not work.

I still got the new avatar name displayed on admin page “Discussion” and I can select it but the image link is still wrong.

Don’t look into the Discussion settings, create an anonymous comment and look at the gravatar there.

I made one, but the url is still broken.
The error looks the same, with the gravatar url still showing up somehow.

Can you show me the code you pasted in full, as well as the gravatar link generated in the anonymous comment?

Sure.

Here is the code :

add_filter( 'avatar_defaults', 'newgravatar' );
function newgravatar ($avatar_defaults) {
    $myavatar = get_bloginfo('template_directory') . '/img/avatar.png';
    $avatar_defaults[$myavatar] = "Own";
    return $avatar_defaults;
}

And the url for anonymous comment :

<img height="80" width="80" class="avatar avatar-80 photo avatar-default" src="https://0.gravatar.com/avatar/?d=https://localhost:8888/mysite/wp-content/themes/rttw_v2/img/avatar.png&s=80" alt="">

You ignored the code snippet I gave you above with the pre_option_ filter.

Oh yes sorry, it was here but just below :

add_filter( 'avatar_defaults', 'newgravatar' );
function newgravatar ($avatar_defaults) {
    $myavatar = get_bloginfo('template_directory') . '/img/avatar.png';
    $avatar_defaults[$myavatar] = "Own";
    return $avatar_defaults;
}

add_filter( 'pre_option_avatar_default', function( $value ) {
	return 'https://localhost:8888/mysite/wp-content/themes/rttw_v2/img/avatar.png';
} );
