New Update (3.7.1) Doesn't Work

@chrismonty I’m so sorry about that! We released the first Quick Cache update in over two years and there were a few unexpected issues with the update, however we addressed those issues immediately in follow-up releases.

The latest version (v131206) properly checks for compatibility before activating itself and includes many bug fixes and improvements. See http://ww.wp.xz.cn/plugins/quick-cache/changelog/
