I found the code of that place but don't know what's wrong there.

<a href="{$lastpost_link}" title="{$full_lastpost_subject}">{$lastpost_subject}</a>
<br /><i class="fa fa-clock-o" title="{$lastpost_date}"></i> <span class=smalltext>{$lang->by} {$lastpost_profilelink}</span>

^ which plugins you have in active status ?

Are you also getting the above issue in default MyBB theme ? If yes, then it is definitely issues with functions_forumlist.php
Make sure you download the file from MyBB github or get it from the original MyBB package (https://mybb.com/download/)
