Can’t change default Gravatar

Given that the error code was one line 1, did you ensure that you added your changes after the opening <?php tag in functions.php? Did you inadvertently duplicate the opening <?php tag?

I put both methods after the <?php tag. No I didn’t duplicate it either. I actually changed the default gravatar using method 1 on my community site with success. I would prefer method 1 myself, but whatever works I guess.

Method 1 is to put this in the functions.php file like so:

add_filter( 'avatar_defaults', 'newgravatar' );

function newgravatar ($avatar_defaults) {
    $myavatar = get_bloginfo('template_directory') . '/images/buildinternet-gravatar.jpg';
    $avatar_defaults[$myavatar] = "Build Internet";
    return $avatar_defaults;
}

Method 2 is to change this:

<?php if(function_exists(’get_avatar’)){ echo get_avatar($comment, 50 );} ?>

to this

<?php if(function_exists(’get_avatar’)){ echo get_avatar($comment, 50, ‘https://www.wphacks.com/wp-content/themes/HackWordPressPro/images/nophoto.gif&#8217;);} ?>

I tried this method again. But placed it at the end of the functions.php file instead and it works now.

Right after this:

<?php
} // </li> is added by wordpress

but before ?>
