I seem to have encountered the same problem as before: the variation information is not being displayed. I am using the latest version updated through WP.
When looking at the page source I can see a product_details div under product_meta, but there is not data inside it. (same as before)
I would like to provide more information but I haven't been able to find any more relevant information. Can you suggest how I can get more debug information so you can fix it?
