Strange php error log entries

[sadams101]

For the past couple of days I've seen this error repeat over and over in my php error logs. Does anyone know what could be causing it?

I would suggest first of all switching to a default theme and checking if these are logged then, as it looks to be coming from your custom theme

[Ryan Ashbrook]

As Marc mentioned, this is likely an out of date theme. Specifically, the forums > topics > topic template. If you open that template in your theme, click the Variables button and make sure it looks like this:

$topic, $comments, $question=NULL, $votes=array(), $nextUnread=NULL, $pagination=NULL, $topicVotes=array()
