Same issue, updated to 3.0.5 and now all attributes not working. If I delete and create the attribute again, delete the variations and re add then works. Painful for over 30 products so I would love to see if there is an easy fix.

I downgraded to 3.0.4 and the variation products work. But checkout doesn’t and it throwing up 520 errors.

It seems like this is a really bad woocommerce upgrade…

Same problem here. Painful!

I actually went through and re created my attributes and variations, time consuming but it worked and no issues with on checkout.
Yeah seems to be some big issues with it, also another client is having issues with a calculator system in woocommerce, expect it to be the same problem with 3.0.5

GRR this has affected me too. I have a MASSIVE store, it would take me weeks to re-do all the attributes.

I am livid!

Same here. Waited for theme updates, but no dice.

The one thing I noticed was that only variable products with custom attributes (attributes created within the listing) were affected. Most, if not all, of my variable products that worked from a set of saved attributes seemed to be fine.

With ~300 variable product skus, I don’t plan to go through one by one and duplicate listings. Can’t even go into the original one and add it, because the variation tab won’t see the attribute in my existing listings, they all have to be duplicated via copy and paste. Ain’t nobody got time for that!

I’d be happy to hear anyone’s solutions, otherwise I’m holding out for further updates and testing then. Ridiculous though…

Edit: Also disabled all plugins and tested with 2017 theme, but the issue persisted.

just to update the developer and everyone else. the new fix didn’t work for me. the only thing that works at the moment is to revert back to a developers version 2.70, at github.

I’m having the same issue. Didn’t happen until I upgraded the woo templates.

3.0.6 Fixed my issues. Thank you!!
