So I tried out this mod and tried tweaking it so that the background appeared behind the username and I had a problem with the formatting.
I attached the screenshot I took.
And here's the code I used
// Show information about the poster of this message.
echo '
<div class="poster">
<h4>';
// Show a link to the member's profile.
if(!empty($modSettings['TopicAuthor_enable']) && $message['member']['id'] == $context['topic_starter_id'])
echo'
<span class="topic_author">', $message['member']['link'], '</span>';
else
echo '
', $message['member']['link'], '
</h4>
<ul class="reset smalltext" id="msg_', $message['id'], '_extra_info">';
any ideas on what's causing this?
