I’m getting the fatal error message: “Fatal error: Call to a member function quickUserCan() on a non-object in /opt/wikihow/prod/includes/diff/DifferenceEngine.php on line 506” when trying to patrol: http://www.wikihow.com/index.php?title=Track-Children’s-Yahoo-Messenger&rcid=13598555&namespace=&invert=0&associated=0&reverse=0&redirect=no&fromrc=1

Thanks Lutherus! The problem was that I had renamed the page without leaving a redirect behind (to get it more in line with commercial policy), but the original edit hadn’t been marked as patrolled yet. When I took your link and adjusted the title to the new version, I was able to mark it patrolled, so it’s now out of the queue. That issue should be pretty rare (when there’s a redirect, the link will go to the right place, so it’s only the non-redirect ones that would cause an error like that), but let’s look out and see if it happens more in future, in case we need a bigger fix. Thanks!
