I have updated it 3-4 days ago.
I did not notice any change in my site, except it is written 3.6 now 🙂
My woocommerce checkout page is missed up now and the css aint working nor the javascript after updating to 3.6 😀
@rayo2010, I have face this problem before 2 week after installing the version 3.6.
Now if you have the woocommerce folder in wp-content\theme\your theme\woocommerce, than please rename or remove the chekcout folder in it.
I hope it may help.
for some reasons the problem was in wp-include , once i replaced it with wp-include of my testsite which is also 3.6 and works fineevery thing worked fine ….i still wonder why?!!!.
@rayo2010, yes, it may happen, because sometime whenever we are upgrade the version at that time, it may not fully update, so we should have to put wp-include and wp-admin folder manually to our site. After that it can work perfectly.
