WordPress is up to date, using up to date woocommerce and meta slider plugin. Theme is from elegant themes so i don't think the issue lies there, but it may just be. Store works aside from the variations, sell almost every day.
Issue: I have multiple stores with product attribute & variations working on other websites using the exact same plugins. For some reason I have struggled to get it to work on this install. The variations will show, but when selected there is no add to cart function and you can't purchase.

You can select different types but not purchase. I also installed a different theme also used and working with other websites, but that too had issues unlike the rest of my installations. I feel there may be some php coding issue, maybe I drank too much wine and deleted something one night, but don't think so. Any help would be greatly appreciated, I've struggled to find my problem for months now.
