(WooCommerce) Are you experiencing a re-direct admin login issue after upgrade?

I felt it was prudent to post my solution to this problem here, as it took me most of the day to find.

If you have just upgraded to WooCommerce 2.2.11, and are experiencing a browser re-direct that eventually triggers an error such as this:

This Page isn’t re-directing properly – This may be caused by cookies

The answer is actually very simple. All you have to do is disable > clear > then re-activate your server side caching feature (Memcache specifically).

That should fix this issue entirely.

If this post can help even one person stop chasing their tail, or restore a massive backup, than I’ve done my job.

Thanks!
