I tested this but here comments are displayed without an error message.

The file you mention contains this code at line 92:

<img class="gravatar" src="//www.gravatar.com/avatar/<?php echo md5(strtolower(trim($_smarty_tpl->tpl_vars['comment']->value['EMAIL'])));?>

The error message you can see seems to indicate that there is a problem with HTML syntax produced by that template file.

When I look into the source code of your website I can see a bit more of the error message. It seems that the EMAIL value is undefined.
Can you check whether you have defined an email contact in Piwigo?

That is not about the site's email contact in Piwigo, but the comment author's email. The Bootstrap Default theme tries to fetch the corresponding avatar image, but does not check whether email is actually set, see themes/bootstrapdefault/template/comment_list.tpl line 34.

You could either fiddle with that theme code to pull the gravatar image only if email is set, i.e. by replacing

            <img class="gravatar" src="//www.gravatar.com/avatar/{$comment.EMAIL|trim|strtolower|md5}?d={$http_scheme}://{$smarty.server.HTTP_HOST}/{$ROOT_URL}themes/bootstrapdefault/img/user.png" />

with something like

            <img class="gravatar" src="{if isset($comment.EMAIL)}//www.gravatar.com/avatar/{$comment.EMAIL|trim|strtolower|md5}?d={$http_scheme}://{$smarty.server.HTTP_HOST}/{/fi}{$ROOT_URL}themes/bootstrapdefault/img/user.png" />

(untested!)

or suppress PHP messages altogether, i.e. in local config have

$conf['show_php_errors_on_frontend'] = false;

or fine tune message classes to display, see [Forum, post 183126 by erAck in topic 31852] Menubar tags issue after 12.2.0 upgrade, or better, log to file instead.
