Bootstrap Ultimate WooCommerce Variable Product not showing options

Hi there.

I’m using WooCommerce on my site, and I’ve run into the problem of variable product types not displaying an add to cart option, or the drop downs to select the product.

I found this isolated solution, but it didn’t seem applicable.

I tried it anyway, and it didn’t solve the problem.

Any ideas as to why this would be happening?

Thanks.
