Hi SpeedyWP:
Thank you for trying to use this plugin.
I’ve just went to update my development installation of WP and WC. For me, everything have worked like a charm.
I would like to suggest you, if you haven’t already done that, to view a small video that I’ve created with a walkthrough for default use of it — apologies for my english ??
Please visit it at https://vimeo.com/51533811.
Having your description in mind, I’m inclined to point you that this plugin doesn’t yet support custom product attributes. Instead, you should create your attributes inside Products tab and then call these Attributes inside Attribute tab on Product Page definition.
On the other hand, i’ve also created a product without variations and had no problems with it.
Please, notify me if you are know on the right track.
