Pal74 on "[Plugin: WooCommerce - excelling eCommerce] Variations not working"

Hello! I have the same problem.
I read first what you were suggesting and followed you instructions. I saved every single step when adding a new product.
It did not help at all - it keeps deleting the check-box for "use for variation"
What is more, the check sign already disappears when adding a product, save that step and go on with editing...
