In 12.0.1.15778, the More Content widget when set to users and the user displays a bio, the existing code (in User.vm) reads:
<a href="$core_v2_encoding.HtmlAttributeEncode($item.Content.Url)" class="internal-link view-full-post navigable"> <div class="content">$!core_v2_language.Truncate($!item.User.Bio(), 200, '...')</div> </a>
Which returns "$core_v2_encoding.HtmlAttributeEncode($item.Content.Url)" as the URL for the user and errors out.
Easy solution:
Match the URL to the User's Profile URL instead.
<a href="$core_v2_encoding.HtmlAttributeEncode($item.User.ProfileUrl)" class="internal-link view-full-post navigable"> <div class="content">$!core_v2_language.Truncate($!item.User.Bio(), 200, '...')</div> </a>
add reference to user.vm as location of code within widget
