RC2 Debug error - Undefined index: mark_time

[Volksdevil]

Testing 3.1 RC2, Upon enabling Debug I get the following when viewing a forum:

[phpBB Debug] PHP Notice: in file [ROOT]/viewforum.php on line 474: Undefined index: mark_time

Sorry if this is in the wrong place, I never know where to post this type of thing. In the tracker? But then I'm not sure if it's an issue across all installs. At phpbb.com but then it says don't post bug reports. So here it is.

EDIT: An update. If I go to 'Load settings' and find 'Enable server-side topic marking:' and set it to 'No', that's when the debug message appears. If I set it to 'Yes, then the debug message is no longer there.

What gives?

OK, Just so you know...After upgrading from PHP 5.3.3 to PHP 5.5.9 the error is still there.

This isn't a PHP problem, it's a phpBB problem - so updating PHP will have about the same usefulness as a fly swatter at a tennis match.

LOL fair point in that I don't know why I posted that here. I know it's not a PHP problem per say, but rather a PHP code problem. (Missing code from what I can tell).

PS: I did have to update my PHP Version to get around the following error with the Admin Contact page https://tracker.phpbb.com/browse/PHPBB3-12865 but that's of course another topic, more like a Tennis racket in that case.
