Hello, I have exactly the same issue.

I recently updated enfold to 3.6.1 and Woocommerce to 2.6 and now to 2.6.1.

Since these updates, the Update cart button on the cart page doesn’t work anymore.
When I am on the cart page and change the quantity of a cart row with the plus and minus buttons and then click the ‘Update Cart’ button, it doesn’t update the quantity. It only works when I type the new quantity directly in the quantity input and then hit the Enter key.

I have no console errors and no errors after activating the WP_DEBUG mode. No caching is activated on the site.

I deactivated all plugins but woocommerce but the issue was still there.
Then I switched to the default Twenty Sixteen Theme and the issue was resolved.
So the issue must come from the enfold theme, more specifically since the last enfold update to 3.6.1 because before that update the button worked.

How can we fix this problem – at least temporarily until the next theme update?

Thanks in advance
