Carolina,
Insert this code in your child theme’s function.php:
function my_avatar_filter() {
// Remove from show_user_profile hook
remove_action('show_user_profile', array('wp_user_avatar', 'wpua_action_show_user_profile'));
remove_action('show_user_profile', array('wp_user_avatar', 'wpua_media_upload_scripts'));
// Remove from edit_user_profile hook
remove_action('edit_user_profile', array('wp_user_avatar', 'wpua_action_show_user_profile'));
remove_action('edit_user_profile', array('wp_user_avatar', 'wpua_media_upload_scripts'));
// Add to edit_user_avatar hook
add_action('edit_user_avatar', array('wp_user_avatar', 'wpua_action_show_user_profile'));
add_action('edit_user_avatar', array('wp_user_avatar', 'wpua_media_upload_scripts'));
}
I have the same error with WooCommerce Social Login.
