I am so thankful I came across this thread, I just had a white screen after updating the Woocommerce plugin on the latest version of WP (V4.3) (on the latest version of the Divi by Elegant Themes theme).
I've just tried this fix and I can confirm it worked a treat for me - I've reactivated the updated Woocommerce plugin and everything is working all A ok now.
Thank you so much to the person that came up with this fix, I can't thank you enough!!!!
