I've been working on my site for over a year trying to get all of the woo-commerce bugs out (every update), creating listings and attempting to take my store live.
I finally upgrade to 3.6 and ALL of my listing variation attributes are now gone (except 2) - I have over 900 products I need to now re-create. I've never wasted more time - this is VERY disappointing.
Do not download this piece of crap - it's a constant headache. The developers are obviously retarded and don't know how to test their products before releasing them. I'm done wasting my time and energy on this crap.
